Inducer Motor power issue

last year

I have a Bryant plus 80 that went out, and it appears to be an inducer motor issue. The flywheel spins freely, so it isn’t jammed or seized, and when the call for heat is triggered, I can see it jump slightly, but won’t start up and spin. Am I not getting enough power to the motor and need to replace the control board?

A pro has the right diagnostic tools to answer the question without guessing. That's your best approach, if possible.

Thanks, I was hoping it would be something I could manage- I live extremely rurally and currently my 13 mile dirt road is snowed in so getting someone out soon isn’t exactly an option, but it looks like the wood stove will have to suffice until then.

Hey Ya'll, I'm back with an update and a new question. First, it turns out the bench supply I used did not actually fry itself but went into a constant voltage memory status, that needed to be cleared by multiple on/off switch cycles. In the meantime I purchased a 60w(24v/2.5a) single supply that i tried to use but had to return because it just didn't have enough pwr. The inrush current was just to high. So I got a 100w (4.5a) and it worked well. I also put a diode and cap in parallel. Now forward a month, it stopped working. It seems that the 100w doesn't have enough pwr now. Im assuming its the overvoltage light is blinking and the fan doesn't spin that fast. The solar panel ckt doesn't move it neither. Can a sign of a bad motor/brushes be that it needs more juice? The fan blade never looked like it was balanced right and Im curious if that might have taken its toll on it.

I'm an engineer (not a garage door expert). Couple of thoughts: Can you take the cover off the GDO, and with a multimeter make sure you have 120 volts on the circuit board. Do the GDO's have an internal fuse / circuit breaker? Google your GDO model and find out how to jumper the safety lockout.

It is possible the filter is too restrictive, but likely not the problem if you have used the same filter in the past. Have you recently closed any of the supply vents? Are the dampers to the zones operating properly? When was the last time furnace has a preventative maintenance check? The furnace is shutting down due to a safety issue. You need to have this have a professional determine the cause and the fix. Since it is only 6 years old you may be covered by the parts warranty. Call the company who did the installation if you feel they are competent.

If you are snowed in on the backroads dianoising it isn't going to help until spring thaw when you can go for parts. It sounds like motor has gone bad,jerry rig another small motor or a high wattage light to the inducer wires to see if they work as they should. Better still use a volt meter to test voltage.

What is the model number of your Bryant furnace? Carrier/Bryant publishes troubleshooting guides to help isolate the problem. If you furnace is showing a fault code, this will also help narrow it down the problem.

I don't recommend poking around in your furnace unless you know how to read a circuit schematic, know how to use a voltmeter, and are comfortable putting you hands near a hot circuit.

Some inducer motors have start capacitors. If that's the problem, you're looking at about $300-$400 to replace it. The cap itself is about $30.
