Mine did this exact thing and I took it over to Carrier. I spoke with the technician directly and he said the sensor was bad so he replaced it along with the wire that attached to it. Been working fine ever since so far.

Thank u so much for this video.. I just bought a truck last week with the comfort pro apu . I fired it up an it ran for about an hour an it shut of an gave me the exact scenario you did here I did not know what to do..Now I do

I had a problem today with this sensor. I am parked at a receiver all weekend. I pulled the wire towards the sensor and zip tied it. And it is working finally. But thank you for the video it really helped

Thanks for sharing, it helped me solve my issue

Thx so much you saved my ass tonight...

The temperature sensor and several other issues can be caused by a bad ground. The temperature sensor is just a switch that opens at a designated temperature to interrupt a circuit by removing the ground. If you have a test light connect the clamp end to a 12 volt source and touch the probe end to the terminal on the temperature sensor. Your test light should be lit. If not make sure the sensor is grounded by touching the probe to the base of the sensor. If you don’t get light corrosion or too much thread sealer has insulated the sensor from ground. Attach a jumper wire to a good ground and clamp it to the base of the sensor and again check it with your test light or just start your apu and see if it runs. Just grounding the wire to the sensor will make it run but if it does overheat it won’t shut down….so don’t!

gracias me ayudo mucho

Glad to see that you stressed not to over tighten the sensor. So many times the sensor would get replaced, over tightened, a week later the unit was back with the same issue. At that point the tech would call technical support, and he would talk to me.

Thanks good information

Thank you for posting this video. Your symptoms are identical to mine. After watching your video I went and bought the sensor which is now around $120 as mine has been retro fitted. After installing it earlier today. It is running tonight without problem. Thank you once again for posting this.

I work on these all the time in my fleet two well 3 are sensor or the wire or both and the fuel pump top of fuel pump have one way valves and they wear out and allow fuel you flow back out of line or the factory clamps allow air in the line other then the small problems its a good unit

Thank you

I broke mine inside it was tighten almost all the way, took hell of time to find right person to take it out.

Hey good morning sir! I replaced the sensor but I’m still having the same issue. Where did you purchase the wire harness?

Thanks.

Can you tell me what type of unit you have. I have the same one. It starts with a PC600 or 220

Is it normal to have oil or how much oil on your top of the engine it’s like the injectors I think

Please you know what’s the part number for the temperature sensor

What’s the part number for the sensor and where can I buy it? Having same issue Thanks

My apu will not crank turn just once sound like weak battery but the truck starts with no problem?

Mine says overload ! I replaced alternator belt because it broke. Any idea how to clear this code or what else maybe wrong

At the 1:55 mark, the hose that you have your hand on, mine isn't connected to anything and the a.p.u keeps shutting off telling me to check the engine. Is it supposed to be connected to something? I'm new to a.p.u's

Clint Bulloch That's an overflow tube. It's not supposed to be connected to anything. What fault light is lit up in the back of the apu?

How do you turn the water off to the apu.

My apu runs fine on its own but when I turn the ac on , it shuts off .

How about the oil pressure sensor?

Okay Robert the heat sensor for where it overheats has been replaced the thermostat has been replaced but every time I turn on the AC unit itself it shuts off both oil and coolant are full? What's next

I’m having the same issue. I haven’t resolved this yet, but noticed the condenser fan is not kicking on on the back of the truck as well. I am wondering if the fan is bad. The app runs fine and never shuts down as long as I don’t turn the AC on.

The coldest mine gets is about 87 degrees in the cab at night you can get into the 60s but that doesn't count because it's only about 70 at night what do you think could be wrong

Low refrigerant. If the condenser hoses are not protected when routed into bunk, the body sheet metal will run/cut the hoses...I know. I just had this happen. Fortunately (4)hose clamps, a 3/8” barbed union and 4 cans of 134 got me going. I plan on pulling unit down to a vacuum and replacing the filter drier.

This is exactly what happened. Hopefully it’s in stock 😮

Where is the oil pressure sensor located

Will the sensor cause to have main engine interlock?

@TheHitchiker42

3 жыл бұрын

If the DCP indicates Interlock, it means that either the interlock is wired in and the key is in the on position, which powers up the circuit to let the system know the main engine is running, or there is a fault in the harness, can't remember the pin number off hand.

My husband has had the alternator replaced 5 times in a year on his Comfort Pro. We have no idea what us happening with it. Thoughts?

30-266-01K . That's a very common number for the Kubota Z482 used in the PC6000, PC6002, etc. Should be the same in all the models since the engine hasn't changed. To the best of my knowledge its a normal open (no continuity from the terminal to ground) and closes (grounds out and causes shut down) if temp reaches 245°F

Please sir I have Apu it run fine but the A/c is not working. I tested the fan and the wire is fine . I open my sleep bed and check the motherboard that the a/c get it power from no power. Don’t know if it has a fuse or the motherboard is damaging?

Anyway The only 2 codes after 8 nites is engine overheat! Not 8 codes just 2.

Where is the APU breaker located

@gradycothren2267

3 жыл бұрын

If the display shows ccu main breaker trip or HVAC breaker trip, both of those can not be reset by hand. If you press clear/reset on panel, it will go away. If it keeps happening, the household power voltage (110-115V) could be too low to run your air conditioning compressor/microwave..etc. This is most often caused by faulty capacitor for apu generator located on rear panel inside apu under the radiator. It is a 40 microfarad capacitor. One way to check if it is bad, use a multimeter set to VOLTS A/C and test at power outlet with unit running. If 105 or below, it is weak and needs replaced. If doing it yourself, remove the bolts on lower cover (1/2 in.) Capacitor is a silver and black cylinder with 2 wires. Cut one at a time, never both together or electric shock could happen! Strip wires from apu back and install new capacitor with hardware it comes with (butt connectors to crimp on using crimper pliers with heat shrink and capacitor holder and nut.) Does not matter which wire you connect first and where, it is universal. Warm up the connectors with a lighter to shrink the connector wrap and zip tie the extra wires up to keep then off the exhaust. This should fix most instances for breaker reset but if not, theres trouble with the main board under the bunk or wiring to it. Test output voltage with unit on, should be in 115-120 volt range.hope this helps!

Mine is doin same thing, did you figure it out

I have the same problem of my unit shutting down for no apparent reason. In the picture next to the guys hand there is a little Red wire that comes forward and attaches to what looks like a small plug. That is a temperature sensor. Sometimes the wire becomes lose, and the unit will shut down. At some point I am going to get a new wire and sensor installed, but for now a really tight mini zip tie keeps it snug and the unit runs. I read somewhere that there was a recall on a Comfort Pro sensor, but every time I go into one of the Carrier shops they treat me like an idiot, charge me $ 200 , never tell me what they are doing except for that it is a lose wire and all is good now. Well it runs for a few days until the roads jar the wire lose again and the unit will only run for a few minutes or hours but always shuts down until I re secure that little Red wire. That is my experience and what I have done to resolve the issue.... G
