Thank you so much for this! I have a brand new variable speed Goodman Furnace in my attic for my second story. When I turn the heat on, heat will come through the registers for ten minutes. Then the inducer motor will shift into a high gear and make a very Loud noise for 90 seconds. It's so loud it sounds like an airplane is taking off. After 90 seconds the inducer motor will either shut down, or shift to a quieter speed. When this happens, all heat will stop coming through the registers. The heat shuts down before reaching the temp the thermostat is set to. My HVAC contractor tried to trouble shoot by taking off the NEST thermostat and hot-wiring the thermostat. Nothing changed. Heat flowed for 10 minutes. Then the inducer motor sped up and sounded like an airplane for 90 seconds. Then the inducer quieted down and the heat shut off completely. Now, my HVAC contractor has no idea what the problem is. Any idea what we should be checking? (Also, my HVAC contractors said there's nothing I can do about the loudness of the inducer motor. It's not due to vibration so suspending it won't help. Plus my attic ceiling is too high to suspend it. I'm in California. He said this type of inducer motor is only required in California. Is there anything I can do about the LOUDNESS??) Thank you again!

Brother in law calls and says his furnace is not running 60 in house. Used an Ohm meter and found 120V at the inducer blower leads but inducer not running. Watched this video. Then went back to the brother in laws house next door. Was just about to think the inducer blower was bad and tinkered with the leads to the unit at the connection on the blower, and by jarring one, the blower began running. Used a TWISTIE TIE to keep tension on the one wire closer to the other so the blower works and now the furnace runs fine. I fixed his furnace with a TWISTIE TIE--only thing handy at that moment!!! Tomorrow I will review the work and maybe use a zip tie instead. I doubt there is any cure for a bad factory made connector that I can repair and I sure am not going to buy a whole blower.

Always check the t stat and filter first and the the overtemp switches but, Its usually the bearings in the inducer that go bad. Just spinning the motor like you showed can usually show a problem. This can often cause the relay on the board to fail. I just usually power up the inducer motor with jumper leads if it looks ok to test it.

@CityWineDenver2 жыл бұрын
I found my induction motor would not always start up and it seems to be due to "play" in the way it is attached to the housing (perhaps just from time, since it is over 20 years old). I could not find a way to tighten things down to the housing / mount, so I attached a strap to help secure the motor. It had to be in the right place, so I've needed to tweak it. However, not sure the strap will stay put long term, but it seems to help stablize the motor. It seems the only real fix is to replace the motor, they come with the mounts... I was hoping for a less expensive fix. Ideas welcome.

I live in an apartment complex of 110 units, and we have had several inducer draft motors with bearing failures that often don't get replaced right away, but make noise that I can often hear months before the tenant or landlord hears! Anyway, I was curious why these motors run ALL THE TIME, even when just the AC is on! Does the inducer draft blower serve any function when the AC is running, and if not, why have it running for hundreds of hours during the cooling season if it's not needed? One other issue: in twenty years, my unit needed service when a hornets' nest was built in June 2005, my first year here. I've learned since to run the heat (furnace) five minutes a week during the time from about April until the end of June, to discourage pests! - j q t -

I have a problem where I hear the humming current going through my inducer motor but it's not spinning. I turn off the furnace and start up again and the inducer motor does the same thing. I thought it's the capacitor so I bought a new replacement but it's doing the same thing. I tried spinning the motor by hand and it would go slowly with resistance. But once I turn the furnace off I am able to spin the inducer motor freely. So I don't think the bearings are seized. Any idea to what might be wrong?

during normal operations the inducer runs constantly. without stopping. if I short cycle(my own term in which I turn stat up requesting heat and once squirrel cage engages I physically turn stat down 10 degrees below ambient; blower stops & internals retained heat raises enough for a second blower run to cool- maybe a minute or two. After this "short cycle" when blower stops the inducer also stops. I find this as the only way to stop inducer motor. What am I experiencing?

The inducer on my Heil 80% single stage repeatedly cycles on and off when the furnace is not calling for heat. After the furnace fan cycles off, the inducer runs on and off for about 20 minutes. Pressure switch checks out for proper voltage, tubing had a few drops of water in it. No vent obstructions either. I turn the furnace down to 58 degrees at night and this is when it occurs.

When the thermostat calls for heat the inducer motor turns on then off immediately. Three lights flashing. After a few minutes it trys to start again. It may do this once, twice, 3, 4 times before it stays on. This doesn`t happen all the time. For a week it may start every time. Its an erratic issue. When this happens: thermostat is sending 24 volts to the board. there is no power to the inducer motor from the control board, I can hear the blower relay click on then off, so I replaced the control board. Same issue. I replaced the inducer motor. Same issue. I replaced the pressure switch . Same issue. Thermostat is new and performing as it should, it is sending 24 volts to board. Wiring is good.

We usually try to build a temporary shelter if possible to keep the rain off. I know there is only so many things we can fit in the truck and for a service tech, it is hard to tell what the day holds or what if any special precautions you would need to take ahead of time. You could use one of your towels from the truck to gently wipe off the components and then for something like a control board use a heat gun far enough away to dry the water off the board without getting the board really hot. You seem to understand what is needed and am sure you will take precautions when needed. We just do what we can but we don't work on live electric in the rain or stand in water puddles while diagnosing live equipment. Just stay safe and try to communicate your concerns to your boss and try to think of every precaution you can take to get the job done. In a scenario like that, it is easier when you are the boss because it is easy for you to make the call. Other than that being a boss isn't easy ha ha.

If the motor does say”sealed bearings” and only has a hole in the front toward the blower wheel, can you oil it? My motor was stiff. I removed and let it run on the ground. It started a little slow, but started running. I heard something loose in the housing when I removed it. Found a piece of gravel. Not sure if it was in it already, or if I somehow got it in it when I laid it on the ground. I don’t think I did actually but have no good idea how a piece of gravel from the drive could have gotten in it. Rodent? Also, the motor only has two wires going to it. They honed at 49 ohms I think it was. It is a 220 volt motor.

The problem is you dont want that to be running with stiff bearings and catch on fire. That is a real thing that seems to happen to inducer motors more than any other component. You may want to consider replacing that, thanks
@rickeykeeton714 жыл бұрын
AC Service Tech LLC I meant to say the motor is notstamped “sealed” I did get the motor spinning a little more freely, but only ran for a little bit. Getting back on it today as was dark and cold when I last checked it. I suspect the bearings got hot and caused the motor to overheat. Not sure I am getting power to the motor now as it did seem to get warm like it first did when I noticed it. I will check for 220-230 at the board that supplies power to the two wires going to the motor again. I do think It is best to replace the motor since the windings, bearings and or thermal protector may be damaged. I had thought of replacing the bearings, but this thing is about 19 or 20 years old. The only service it has ever had was when I cleaned the coils a time or two and replaced capacitor. Does 44 ohms sound right for the motor? It only has two wires going to it, red and yellow from the board. Found the immediate problem. When I bundled the wires up again with the zip tie, I pulled a blue wire off the relay. The motor was still very slow to start, but it did eventually get up to what I think is the correct speed and the heater fired up. Going to let it run a little and check the motor for getting warm. Update: I let it run for a little bit. I suspected the motor was still stiff because it would move very slowly when trying to run. I boosted a little a few times with a screw driver against the fins inside the motor until it got moving faster and it finally got up to speed. but, it got too hot to lay my hand on for very long. Motor time. :(

I know that doesn't necessarily mean it's clear, but basically, my pressure switch isn't activating. I tried taking the tube off of that and feeling for a vacuum, but I couldn't detect any with my fingers... Should I be able to? All signs are pointing to the pressure switch, but the undetectable vacuum made me second guess that. Any suggestions would be really appreciated!

@@learnjcbskidsterchickensga7594 I made a manometer with some colored water in a loop of vinyl tubing and confirmed that it had an adequate amount of vacuum. So, it ended up being the pressure switch, and I found one locally for less than $10!

Hi, I am Very thankful your posting and i wanna to ask that My furnace is working but the combustion air inducer seem like very very hot when the prowler is on. I am afraid that is abnormal or is fine? Do I need to change it?
@acservicetechchannel5 жыл бұрын
It will get warm depending on the % eff of the furnace and how hot the exhaust is. If you are concerned then it could be changed. If the bearings are going bad then they present a safety concern, thanks

If an inducer motor is some how shorted to where it runs non stop would it create a false command for heat, to where the "w" terminal on the control board is disconnected and the inducer motor, blower motor and gas all run non stop except to cycle off for overheating?
@acservicetechchannel5 жыл бұрын
I am assuming that you are talking a variable or ecm motor, in that case, it shouldn't feed any 24v to w or make the furnace think it should be in heat mode, thanks

Darn, well i have all thermostat wires disconnected from the circuit board, furnace is blowing hot all the time except for overheat protection, i do have 27volts at the w terminal and .8 ohms between w and r terminals. I replaced the circuit board and same problem. Am i missing something else or is my problem just shorting out the new circuit board

Hi. I appreciate your channel. I have a Lennox system. The first time I attempted to use the Heat Cycle this season, it did not start the shaded pole inducer motor. No sysytem error messages. I assumed bad motor and replaced. Still does not start motor. I verified thermostat continuity. What should I check next?
@acservicetechchannel5 жыл бұрын
After you turn your thermostat to heat, inside the furnace, do you have 24v read with a multimeter from w to c? If not, you are not getting a signal to the control board to start the heat sequence, thanks!

My guy. My inducer motor keeps running after the cycle. What could that be? The red light is solid. No blinking. The heat comes out good and runs through the entire cycle.

So if I get 0 reading at w and ground with r and w jumped at the thermostat, then the wiring from thermostat to furnace is bad?

Yes if you do have 24v at the board actually going to the R at the tstat

Is there a way to lubricate a motor similar to the very last one you've shown in your video? I have a Bryant 340AAV furnace and the capacitor for the inducer is weak (3.0+-5% is at 2.6). But i also notice unusually amount of stiffness from the motor itself,as well as some minor play in the shaft. Is there someway i can lubricate the unit? I cannot find any ports. Great video btw, I didn't even know to check the tiny rectangle capacitor at 4:55.
@acservicetechchannel5 жыл бұрын
Thanks and no that play cannot be corrected. It sounds like if there is stiffness and play that the motor is on its way out, especially if there are no oil ports. Even if there was, oil wouldn't correct the underlying problem of it being worn down. Oiled motors need to have oil added every six months or so, thanks and yes replace that capacitor.

Any idea why an inducer would PULSE? I replaced the limit switch in September and that seemed to fix it, however yesterday the pulsing has returned?/
@acservicetechchannel5 жыл бұрын
Usually that is due to a restriction in the exhaust such as water filling up a section of the exhaust pipe to the exhaust condensing while traveling through the pipe but the problem is that the piping is not pitched at 1/4" of pitch or higher upwards as it travels away from the furnace. That would be my guess, and make sure to also clean out the furnace condensate line, thanks
