How to test refrigerator compressor start relays

Тәжірибелік нұсқаулар және стиль

The most comprehensive refrigerator compressor start relay testing video on the internet. We show how to test a start relay for continuity and resistance, how to test the compressor overload, rattle test, and much more. When the start relay fails it will cause the compressor to not start and the refrigerator will stop cooling. You may also hear a clicking noise coming from the overload as the refrigerator tries to start the compressor. Some people call the start relay a start device, they are interchangeable terms for the same part.

    Very good video. You know your craft very well. I am an old retired appliance repair servicer but have not serviced a refrigerator since 1978 when I began servicing only TV sets. My refrigerator stopped cooling so I started the process of troubleshooting without any tools or test equipment. The refrigerator has been in operation for 23 years with proper cleaning. I had a severe neck injury six years ago resulting in me not being able to do normal cleaning. I also forgot to clean the condenser coil rack. Both the refrigerator and freezer temperature was 72 degrees with the evap and cond fans running. The compressor was warm with the overload protector cycling every minute or so. When the compressor would try to start the cabinet interior light would dim a little for less than a second. At this point, I thought the problem was a restricted condenser rack. I had also noted that a handy dandy door towel was preventing the refrigerator door from closing properly. I had suggested several times over the years that the door handle towel while cute was bad for the proper operation of the unit. I looked under the refrigerator and saw more lint buildup than I had ever witnessed before. I got out the vacuum cleaner and did a partial cleaning with the crevice\brush tool. The unit began to cool down so I turned the Tstat off and informed my wife that we had bad problems and that she should empty the unit and clean the interior before the repairman could take it to his shop for service. I also told her that I had to clean under the refrigerator and run some tests before calling for service. All of the above has been completed and the unit started cooling for about thirty minutes. I tested the temps three hours later to discover the compressor had stopped running again. Puzzled, I called an old friend to help me pull the unit out from under the cabinets that had been built around the unit. The carpenter had failed to leave enough height for the unit and so it had been wedged under the cabinet with less than zero clearance. The wheels on the bottom had permitted enough give for this to happen. With the unit away from the wall; I was able to completely clean out the condenser and compressor cavity. I think the start capacitor does not have enough capacitance to start the compressor now but I cannot figure out why the compressor stopped cooling a couple of hours following the first partial cleaning. I plan on ordering the start relay and capacitor before deciding to contact one of you younger guys. My wife would love a new smart fridge but with fixed retirement income that purchase will be a "real trick". It seems possible that the compressor start un internal windings may now have a problem that causes something within the windings or the relay to open after a few hours of run time. This could have been caused by the compressor running close to the FLR amps and temperature because of the dirty comp rack and\or the door handle towel preventing the complete door closure for many years. Do you have any thoughts? If a new start relay and cap does not fix the problem; should I have a new compressor installed or purchase a new unit? I will have to quit eating and give up my fast internet service to pay for the new unit. :-)

    Hi Jerry, if the start relay and capacitor don't resolve your issue it usually isn't very cost effective to replace the compressor so we usually recommend replacing the refrigerator. If your refrigerator has a condenser fan motor on the back to dissipate the heat, make sure that it is working properly.

    Very helpful video. The modern start relay in my Maytag failed the shake test but the impedance was OK. It would work but overload every so often. Via an HBN meter I noticed the surge was not excessive, just 800 watts when the compressor started, 150 watts once it was running, so the compressor seems to be in good condition. I disassembled the relay and squirted tuner cleaner on all of the contactors. Lo and behold, it worked after reassembly but I ordered a replacement anyway. I find tuner cleaner will resolve many intermittent problems. While it was out, I checked the capacitor for microfarads. Mine was good.

    Fantastic documentation, great work. Definitely will be visiting PartsDr. Love the shots of inside the start device (3:49), showing how it works. I'm guessing the little "wheel" is magnet with conductive coating on two surfaces, that slides back and forth to complete circuit when needed. My overload (cheap aftermarket) did not have continuity, took apart and it had tiny wire under the disc that had disconnected or blown (not even sure a proper genuine part should have a wire under there). Wondering if it's possible to convert from a start device (combo relay, overload) to instead use the separate relay and overload? For my old Whirlpool ET1FHMXMT01, parts list does actually include numbers for the separate relay and overload (and wire for capacitor). Would only need to figure out the wiring and connectors. Also wondering how those "3-in-1 hard starts" work and look like inside.

    Hey man! Just want to say thank you for the video. I tested my relay and it was bad, cap was good. Ordered both just in case, and my fridge is back up and running! Was $160 with next day shipping. None of my local appliance shops had the part in stock. The fridge is 14 years old so we're going to replace it anyway, but this extra life affords us some time to make a good decision and not feel pressured by availability. If you're taking suggestions, I'd suggest a vid with a cheap/normal multimeter. Fluke is the best of course, but weekend warriors probably don't have that nice of a unit. I had to bridge the two back connections where the wire hardness connects, then test continuity pin to pin on the three pins that plug into the condenser. I couldn't test like you did with your multimeter. Thanks again, and have a great weekend!

    I have the Relay you show at the 1:25 mark and it reads 5.5 ohms and does not rattle. I have the Overload you show at the 2:25 mark and it reads 0.6 ohms. In short, everything works on my GE GBS22KBSBCC refrigerator except the fridge will not go below 40F and the freezer will not go below 33F. So, what would not allow strong cooling .....if the start relay was bad or the capacitor? Defroster, thermistors, evaporator fan, condenser fan are all working and the coils are spotless. I even checked the three prongs on the condenser and got a 8.4 ohm on the two main prongs, 4.5 ohms on the left and 4.2 ohms on the right. My Embraco 1PH condenser has a label on the side reading "LRA of 11.5 EGU 70HLC' 115 - 127 V". My multimeter read 0.8 amps when it is running. The Capacitor multimeter read 11.85 uF (210 VAC 50/60 Hz @ 12 uF). Some history - In July 2016 I did had a technician add R 134a and in October 2018 I had to add an evaporator thermistor since my evaporator coils were an iceberg and it was not triggering the defrost mode; refrigerator was warm but freezer worked fine. NOTE: I made a video of the Start Relay arcing with the Overload when the compressor was called for power; there was just a click sound but no compressor. Then, 90 seconds later, it called on it again and the compressor hummed away. When I took it apart again the Star Relay gave the same reading but I noted it was VERY hot. Could this Relay still be bad but not activating all the time thus overheating because it is sometimes working? If so, maybe this is why the temperatures cannot catch up. With that said, I do not know the spec for my compressor amps but had some hand written notes from the 2006 technician (when he filled my R143a) stating the original amps were 0.7 and after he added 4.5# the amps were 1.55. His notes also read "spec = 1.5 to 1.7 amps). Should I purchase a new Relay and, if so, is it "good practice" to purchase a new Overload, also? They are very pricy at $76 and $80, respectively......for a piece of plastic! ANY direction would be greatly appreciated by you.

Capacitor ("cap") P/N: WPW10662129 Test relay connections with capacitor on the relay. Results: when together I can get cap to charge and discharge thru the start relay, just like it does when it's off the relay. With cap off and on, neither of the lower holes have continuity with each other. The hole on lower left has 0.0 ohms resistance thru the bottom blade of the back of the plug. The lower right hole has no continuity with anything but can be used to charge the capacitor for testing. The upper hole has 0.1 ohm resistance to the top blade on the opposite side. Remove relay cover and visually check. I cannot get combination relay apart without breaking it, so I haven't committed to that, yet. Ohm test the fridge compressor pins again. Make sure the Common (top) and lower pins are within 3 ohms. And the two pins at bottom should read about the sum of the Common with the Start and Run pins. See KZread video... Results: Top and Lower Right : 4.4 ohm. Top to Lower Left: 6.0 ohm. Two bottom pins: 10.4 ohm. None of the pins are shorted to ground. My problem is it suddenly stopped cooling without noises or warning, but I caught it from hearing loud buzzing noise from compressor and relay area, and compressor was very hot. No smoke or smells though, and wires did not seem to be hot. Do you think it's the combination relay? Thanks!

    Having done repairs of all types but not being a master in anything, I've realized most systems focus on the heart of the system, the workhorse. The AC Compressor is that heart. I wish your video focused on testing the compressor. Too often we look to the small parts to heal our wounds. Money is made on those, but be a little more thorough before you throw money into a hope. If we test the compressor always as part of the common tests, we just replace the compressor or buy a new or used fridge unit.

    Testing the run cap and start relay is where you should start. I have come behind other techs who called for a new compressor, and in reality, it was the start relay or run cap. It just happened with an Americana fridge. It was the SR and not the compressor. I replaced the SR and it works just fine. Just saved the. Ustomer hundreds.

    In case it helps anyone I had combination style start relay that would test OK, but trigger overload when in the fridge with clicking noise. Replacing it even though it read OK resolved the issue. This is because by the time you take out and measure the overload, if it's not completely dead it could have reset (this would be especially true if you hear clicking sounds and the fridge works sometimes vs not at all). So don't just take the reading for single reason to call your compressor bad.

    Hi Ryan, I have a question that maybe you can help me with. I have an old Electrolux E42BS75EPS built-in side by side. When I turn on the unit it gets cold in both the fridge and the freezer for about a day or so and then the temp starts to raise in both compartments. If I turn the unit off for a while. maybe 24 hours and sometimes even less it will get cold again but then it goes back warm. I had servicer's come out and no one seems to know the issue. I put a new board in it so I know that's not the issue. My question is...is the refrigerator fan suppose to run constantly? I'm thinking maybe the fan motor has a short or something because the fan works when the unit come on but then it stops spinning after while but I'm not sure if that's normal or not. Any advice will be appreciated.

    Tim USA Thanks for the reply Sir. So I have been monitoring the fridge since I sent this message out to you. I pulled out the compressor fan motor and found that the metal stem from the motor connected to the plastic fan was stuck and would not turn. I used some needle nose pliers and turned it. It became unstuck. I put the fan assembly back in and the fridge works. However the freezer temp would go up and down during the day. No more than 20 degrees but then it goes back down to 0. The fridge compartment stays at 37,38 degrees and goes no higher than that. I ordered a new fan assembly because they don’t sell the motor separately for this particular model because it’s so old (2007). I’m thinking maybe I don’t even need the fan assembly because going up to 20 degrees and back down to 0 isn’t so bad. The food and ice in the fridge remain frozen. Your thoughts? Should I still pull the panel in the freezer compartment? Thanks.

    If the appliance still pulls starting wattage and eventually clicks, is this a sign the compressor couldn’t start and may be bad or the relay may be malfunctioning? After plugging into a larger wire with less impedance, the appliance seemed to work well (for now). Guessing its because less voltage drop. Consistently over the last 4 months my units range temp has gone from -2 to zero up to 7-9. It’s been a rather gradual increase minus two jumps. Thanks for any help in advance!!

    This is a brilliant video, thank you Parts Dr - your presentation and knowledge is exceptional. I do have a question: the relay and overload protector on my LG fridge, I suspect, are both damaged: the start relay gives 30ohms of resistance, but passes the continuity test; the overload protector sometimes passes continuity and sometimes gives resistance readings, even when contacts are very stable. Sadly, LG doesn't specify the exact parameters of the overload protector and doesn't supply spares in my country. The compressor is a 155w one, so I ordered both a generic 1/4 (180w) and 1/5 HP (150w) overload protector for it - Parts Dr, which one would you use, the 1/4 or the 1/5? I also ordered a generic start relay, it was the only one I could find in the country, so I do hope it works. Thank you so much again for your wonderful video and for any help you can offer.

    The overloads a specific to each compressor and we can only suggest to use the OEM overload suggested by the manufacturer. Hypothetically, if you couldn't get access to the OEM overload and had to use a generic, you would want to try using the one that is slightly under rated than over rated. Using a higher wattage rating overload can be a fire hazard and you can also potentially damage the compressor. Hopefully that helps!

    My refrigerator (Samsung RS277ACRS/XAA-0000) stopped working after a power outage. The ohm readings on the compressor are: C-S: 0.4 ohm C-R: 3.4 ohm I was wondering if such a low reading on the start winding is normal for this model. The Start Relay (thermistor, DA35-00135A) was not showing continuity (R = 1300 ohms), so I replaced it. The new one couldn't start the compressor either. When I test the new one, it also does not have continuity (R = 4000 ohms). I do no know if I got a bad start relay, or my compressor is bad, and the by pulling too much current burns the start relays. The overload protector has continuity, and seems to be fine.

    We don't know what is normal for compressor ohm values on this model. Some are normally lower like that. We haven't heard of a good start relay having that high of resistance values. The overload usually protects the compressor and relay from over current situations.

I need part # 1101014 the start relay, but is discontinued with no part I can find to replace it. It looks like the 2nd one on your table next to the wire one. I've found some that resemble it and also found the disk that goes inside but my problem is all of them have different Ohms, 12,15,22 and 33. Which one should I get? I know nothing about Ohms or refrigerators. My compressor has nothing on the paper on it. I already had a Whirlpool repair man come by and never even checked anything. He told me it was the compressor because it was warm and made clicking sounds. Wish I checked KZread before giving $89. away.

The condenser fan works fine, the compressor ohms seem correct - 5.3ohm, 5.1ohm and 10.4ohm. The voltage between the pins is 120v, before it shuts off.

I have switched the fridge on and off, pressed the power freeze + freezer button for 8+ seconds to reset the system; unscrewed the back panel of the freezer - checked that there is no ice block there; cleaned the dust off the coils at the back...The freezer temperature oscillates from 11C to 22C by itself... but never to -20C which is what we need. It's a 10 year old Samsung fridge. Am concerned that maybe it's a broken thermostat rather than the start relay - and me messing with the start relay could cause the fridge to break down as well.
