Question about Goodman GMS90703BXA Heater

Goodman gmnt100-4 blows all the time

Started about a month ago with the central air.the blower would run continuosly and the condenser would cycle like it was supposed that I need to turn on the heat the blower runs but that is it.I've ran thru the schematic and tested all the wires.All the n.c switches are in the n.c. position and the n.o. are all in the n.o. positions.There are five relays on the board but none of them are stuck.(the blower relay I can watch cycle on when power is applied) Am I looking at a bad board or is there something else I can try????

Is it a gas furnace? have you checked your filters? when the blower runs continuosly apon start up most of the time it is a limit tripped. Goodman puts 2 manual reset on the side of the blower motor hard to get at , but 1 may be tripped, i have been on 7 service calls and all the same problem filter plugged and limit tripped.

What causes a condensing unit to run but blower motor will not come on

Most common cause is the capacitor. The top where the wires plug on should be flat. A lightening strike or other power surge will zap it and cause the top to puff up.

Squeaky condenser fan motor on Carrier 3 ton central air. I oiled once 4 months ago and noise stopped but noise returned today. Is there a special oil for the berings?

Usually a light oil.Wd 40.
Most of these motors are sealed bearings,meaning they do not get oiled.When they start making noise it means the motor bearings are getting worn and the motor will need to be replaced soon.

I have got 5 to 6 months out of noisy motors using a light household oil or WD 40.

My intertherm central ac is running short cycles


It most likely mean that the condenser needs to be cleaned up.
At hardware stores and A/C shops, they sell a cleaner for it, get the ECO frienly version. Instruccions are in the bottle.

If condenser looks clean, (that you can see thru it), then check fan motor, it could be going bad not giving the right RPMs. When this happens, it overheats.

If the condenser can't get rid of the heat the evaporator picks up, the compressor overheats and the thermal proteccion device kicks in to protect it from getting damaged..

Don't forget to rate this post!! Good Luck!!

Furnace runs constantly since blower motor was replaced

Sounds like they wired it direct to line voltage , it should run through a sequencer or fan relay to cycle on and off , your seq./relay could be stuck closed to but unlikely being it was just repaired , call the service company back before you do anything they are responsible.

Compressor will not start.

Usually short cycling means that High side pressure is getting to high (due to not working condenser fan, or dirty condenser coil), or low side pressure is getting too low (might have low level of freon or restriction in sealed system). low side would drop dramatically if indoor blower is not running, so if air is not circulating thru evaporator coil, coil will freeze up and low side would be much lower then normal. Here is video how I found issue with package AC not coming on. Thermostat call for cool, but condenser would not come on, indoor blower runs ok.
