    Have you checked for power at the motor leads using a voltmeter?

First - you should be very careful when checking for 'power' with a ohm meter. I'm assuming you are pretty mechanical inclined (if you changed the motor yourself), but - just be sure to 'never' put an ohm meter (set on ohms) across power.

That being said - if you (indeed) have no power coming out of the circuit board - I would check and see if you have power 'into' the board - and generally speaking if you have power to the board but not out to your motor leads you are probably safe to assume the board is bad but not in all cases.

NOTE: Since your motor caught fire - I'm not sure I wouldn't have a "Service Tech" take a look at your problem and the entire unit just to make sure 'everything' is ok.

good luck!

AC unit does not kick in, NO hum from motor, blower on furnace comes on, Capacitor looks good, any other ideas? Could I have a bad motor?


There is a relay in the outside unit that is controlled by the furnace. You need to check that voltage is coming to it from the furnace. If it is then you need to change the relay. High voltage is present in the unit. Turn of the breaker before doing this

No heat from furnace


If this is the first time unit has been fired up, you likely have air in the lines to purge first. Also make sure the gas supply is on/open. and that if there is a fuse present on the control board (likely a 3 Amp fuse) make sure it has not blown (which can happen simply by close proximity lightning strikes.)

Letting the unit go through the ignition sequence several times will purge the line. If furnace "locks out" on third start attempt, shut it off and start cycling it again until the furnace comes on..

This assumes the installation was checked for leaks initially.

Open rollout or open fuse on Goodman


the fuse is located in the circuit board in the blower compartment and the roll-out is located in the burner section and can be a reset-able switch style or the one time fuse link style which is a a small silver cylinder and is mounted in a ceramic piece and is held in with one screw. Both of these are mounted around the opening of the your burner assembly near the opening. This will be near the area of the gas valve.

Burner ignites and goes out (Goodman Gas-fired furnace)


Hi,
The problem you have is water in the exhaust pipe.
Check to see if the pipe has sagged anywhere or if there is a trap in the line.
If you hear gurgling then it is definetly water....
Some times can be hard to find, even a pipe 1/4 full will cause problems. They are very sensitive to flue problems.
Make sure that the flue pipe either runs back to the furnace or out to the outside, a continuos slope either way witha high spot in the middle.
Also check the bottom drain of the blower if it has one, have had them plug and trap water also..

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

No power to ac indoor fan motor


sounds like you might have a bad control board. try putting a jumper wire on the control board low voltage terminals R and G your fan should come on and run if you have 120v power to fan motor. double check that you do have 120 leaving board and going to motor. if no 120 bad board if you do have 120 bad motor. if it is the board it likely has a bad blower relay which is common in amana models and goodman equipment.

I have a goodman furnace and ac unit the fan and heat work but every time i turn the ac on it blows the low voltage fuse ive replaced all low voltage wires to outside unit and thermostat i also replaced...


Look at the contactor on the condensing unit, remove the low voltage wires to the contactor and turn on the system. If the low voltage fuse doesn't blow, replace the contactor.

Goodman furnace


double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again

Turn breaker on to furnace and the exhuast fon comes and ac will not come on


There should be two separate breakers for the cooling system. The furnace breaker you turned on. Now there should be a double breaker in the power panel labeled A/C or Air Conditioner. In addition there should be a disconnect at or near the outside unit. Make sure it is in the on position also. Set the thermostat to cool and the outside unit should start and run.
