Same! Charge $700 for a $100 part, ridiculous

Thanks for the great video. I also appreciate you taking the time to specify the part numbers involved, etc.

Excellent video. Saved me $300 and I completed the job in 20 minutes. One quick comment. Since I did not have a hole in my duct, I used the actuator alignment pin hole and a good flashlight to see if the damper was open or closed. Once I had the damper open everything lined up perfectly. Excellent video, very much appreciated. Thanks again, Chris

Great info! Been struggling with my damper lately. Thanks for the model number for the replacement. Super simple swap.

Fantastic video! You are to-the-point, clear, and well-spoken. Well done!

This is the most clearly explained video on the topic, thanks!

Very helpful video. I was completely prepared climbing into the attic on a very hot day. Took more time getting to the actual damper that it did replacing the motor. Thanks for sharing.

Great video, super helpful. Excellent footage and clear articulation of the problem and solution. Very easy to follow - thx much!

Thank you for the Video! I had a tech come out and install the part, after the installation the second floor was getting real warm, after watching the dampeners and monitoring airflow I realized when he installed it open was closed and closed was open. After watching your video I fixed the issue. Thanks again

This was a very good video. They wanted to charge me 395.00 to replace my old one. I paid 88.50 from amazon and replaced it myself. I live in Reedy fork and this is an ongoing problem. I am just glad I found this video.

Man i wanted to write to you personally and say THANK YOU! I had the exact same issue with the exact same part and had it not been for your video (which was very detailed!) I would have ended up paying a crooked technician about $1000 bucks for this same exact repair. You saved me $900 bucks. Thank you!

thanks for the video. I actually had my furnace stop working the other day. For a couple days it seemed something was wrong. I would put the heat on and my apartment would start to warm up but then never got to where I wanted it. So I would crank up the thermostat a bit more. Results were intermittent. So I thought I better check the furnace. The thermostat was set higher than the actual temperature but the furnace was not working. I turned the main switch off, just like a light switch, then turned it on, I heard a funny almost wheezing noise coming from this round unit attached to the flew. It appeared to be connected to the damper. I'm not an expert on any of these things but years ago I had some experiences which taught me the names of the different parts and structures. Anyway I told my landlady and said I would call the plumber who I got to know a few years ago when he was here about 5 times to fix other issues with the furnace. Sure enough it was the damper motor that wasn't working and it stopped the entire furnace from running. The temps would be going down below freezing that night so we needed to get it fixed. When the plumber came he didn't have the part so he disabled the damper motor altogether so that the furnace would run. We confirmed it would shut off when the thermostat hit the setting. There was no real danger he said, it's just the furnace would not be as efficient. Anyway just another story of how 1 small thing can prevent the entire heating structure from operating.

Thank you! I just had a tech out and told me this was the issue. So he unhooked it completely just temporarily. So I don’t have control of the downstairs zone. But it’s now freezing downstairs. They’re working up a price to replace the motor. He said “it’s not gonna be cheap” but I’m pretty handy so I’m gonna see what they say and do it myself anyway.

Very informative. Answered a lot of questions

Now that was interesting. So I don’t need to use same motor, I can up grade. I replaced the Honeywell control board two years ago with the newest revision. This house was built in 2003 with a two thermostat damper system. One upstairs & one downstairs. One of the dampers for downstairs is always open. This system has been driving us nuts. We also have a make up air duct work. Not good for Houston in the summer. It also has a by pass recirculating duct with a weighted arm so it will self balance. So as I understand how it works. Funny thing, not one AC tech said they could find the controller, Honeywell doesn’t make it any more. My wife the sleuth found it in an hr. in Minneapolis Minnesota. Had to go around world calling service centers that said the same thing. My wife some how got a hold of a service manager in Minneapolis. We had it shipped to Grainger under our company name & got it in 3 days. We work out of our house so that helped a bit for taxes. Just so happens when I was a locksmith in Minneapolis Honeywell was one of my accounts and the service manager remembered me. I was making desk & file cabinet keys for his department. We talked for a bit. When we go up to Minnesota we’ll go out for a beer. Thanks

Excellent Video.

Great Job on the Video. I just had to replaced in my house at $350 each. I wish I had found this first. Question, in another video, it stated that M1 was the hot and M6 the common.

@coolezum this actuator is for the normally open damper. That said, when the system is turned off, the damper is opened by its spring, if it doesn't, something else is wrong with the damper. So there is no need to hold with pliers

My house which I bought a year ago has 3 damper motors and the one that controls the airflow to the master bedroom must be wide open and makes that room and bathroom extremely hot. I am not able to see the brand and model number on the malfunctioning damper motor but the other two seem to be the Honeywell M847D-1004 type. Is it safe to assume that the bad motor can be replaced by the Honeywell M847D-Zone or M847D-1004 one? When the heater starts I see the back side of the bad motor spinning. Does this indicate that the springs inside the motor are bad and unable to open/close the damper? Any suggestions?

Very illustrative and well filmed video. Basically, I checked all the comments posted here and I would like to add some points that I found useful when replacing the motor on ARD damper. As the damper is a power open-spring close system, once the old motor wiring is disconnected, the damper blade must immediately go to the open position. Check that the set screw is pointing to the open position on the label, ensuring that the damper blade is in the open position. Therefore, when installing the new motor, the damper will already be in an open position. The only thing left is to connect the wires. Regarding wiring all you need is to connect two wires : Common (M1) and 24Vac. M1 on the damper to M1 (common) on the control panel and M6 on the damper to the M6 ​​(NO - Normally Open) on the control. The instruction manual is simple, but explains how to replace and check the operation of the engine later. The package no longer includes the Allen key (Hex).

24v doesn’t hurt but make sure the furnace is unplugged to prevent a short to the board.

Is Damper supposed to close when Furnace turns on? Common sense is telling me it should be open to force air upstairs when the furnace is on but then again I'm not HVAC certified.

So if you can’t reach your hand into the damper, how would you make sure that it is fully open when you install the new motor?

What size hex key/Allen key does it need? I tried a bunch I had but nothing seemed to fit.

What does the red switch on the side do? Should it be set to 0 or 3?

If your duct is completely closed off (no slot to put your hand thru), how can you determine valve location? Open? Closed? It seems that this is an important step when assembling the actuator to the valve shaft. Any tips other than cutting a slot in the duct piping would be appreciated. Thanks! Great video BTW.

Hi Tommy. Some actuators have a small lever either at the top (between the motor & the actuator), or on the opposite side of the actuator that you can move around manually. Check that out and let me know if anything is accessible without having to cut a slit in the duct!

My actuator has no light on it?I have a blue and red wire.Red was connected to M6 and Blue to the M1.Anything wrong with the actuator or something need to replaced?

Great video! So how’d you determine before you purchased the damper that your spring was good? Is a spring able to close a damper when motor is bad? Do you know a part number for the spring? Is it as easy to install? Can a sprung damper be controlled with a power-close and powered-open motor? Anybody??

@mjyu6272

Checkthisjunkout if your problem is the damper is closed (not blowing cool air or very mild) when the cool is on, the zone light on the zone board is green (it turns red when the zone board gives a closed signal), in this case, yr zone board is fine and is sending power to the motor and telling it to open the damper, but it the motor is not working or the damper is stuck. You can manually turn the damper open by turning the bolt, you can find it hidden in the back. now you can survive the time before you replace it.

The other damper has an issue not being able to close completely and shut off flow while the air handler is running. (If it closes before the AHU gets going, it can do it.)

where did you buy dampers ?

I don't have the ability to open the duct work to verify that the flap is open as I install the damper motor. Can you see when the damper is open through the alignment pin hole? In theory, if it's open, you should be able to see the flap through the hole.

Hi great video! Question for you, what is the red tab for on the top of the damper actuator? Do I have to manipulate that in any way? The one I bought is set to “0”. Thanks.

Hey Daniel, thanks for the feedback. As long as you tighten the bolt correctly when you install, "0" means the damper is completely closed, where "1", "2", & "3" are different settings you can use to stop the damper from closing all the way. Some people may choose to set their damper at "1" or "2" where others will just set it to "0" and have it completely closed when the thermostat is not calling for air. For example: I live in Texas and it gets really hot in the summer. When it starts to get hot, I may change the dampers to be partially open at "1", so all the rooms get juuust a little bit of AC, even when the room isn't calling for air. The reason I would do this is so that each thermostat/damper doesn't have to work as hard from opening and closing every time the room/zone needs AC. If I have all the dampers (I have 5 zones) completely shut all the time in the summer, the AC unit & dampers will do more work because each zone may call for air at different times, thus the AC unit is running more often than it may need to. In the winter time here (especially with 2 small kids), I want the dampers to shut completely when the thermostat isn't calling for air because if I don't monitor, too much heat isn't good for the little ones. I hope that helps!

This unit is the replacement for the old one he replaced. It will spring back when other zone asks for air.

So I have the same damper in our house all of the other dampers are cold but 1 of them is very hot what does that mean?

Do you really need manually keep the damper open? If the damper is closed when the motor is removed, how about turn the motor to close by the red knob on the side of the motor and then install? So the modes match, it should be unnecessary to cut the insulation cover.
