Fan motor not starting or running

When I turn on the air conditioner, the compressor runs ok but the fan motor is not running at any speed (Lo, Med or Hi). I checked the fan motor and the winding is not open and the thermal fuse is also OK. I tested these latter with an ohmmeter. Any idea what's wrong ?

You can try "bump testing" the motor by connecting a separate power cord to fan motor wires. ensure no power to anything else first. if it spins, then check back to control board and control panel.

Fan will not run without starting it yourself and will not run high speed at all

Sounds like an old unit with a bad run capacitor or

check the components on the board for burnt wiring.

Fans on window units are controlled by a 3way switch. High, Med., and low. Your power and in most cases a capacitor which doubles for the compressor and fan.

So it can only be 1 of the 3
Burnt out windings on the motor
Bad switch
Bad capacitor

Furnace transformer/fan-relay wiring to fan-motor

All you need is 2 fan speeds, 1 for cool and 1 for heat. Leave the low speed disconnected. Normally we have high speed for cooling, and med. or low for heat. So either speed connected to the heating circuit is fine.

Furnace transformer/fan-relay wiring to fan-motor


Sounds like a relay problem but if your fan is running in heating and cooling and operating ok , leave it how you got it. It is possibly the low speed winding is shorted but will be fine with med and high. Sounds like a psc motor, doesn't use 3 speeds

I have a springdale travel trailer with a dometic ac system. When I turn the air on, with the fan in the auto position on the thermostst, the compressor turns on and runs, but the fan does not. The...

Neither.
The fan should run in the 'auto' position.
If it runs (on hi and lo settings) then I doubt if anything is wrong with the fan motor.
I would think your thermostat is bad and needs replacing.

Unit runs for about 5 min the cuts off. whats the problem?

Hi!!
It could be many things, the most common are Low R22 refrigerant, bad fan motor, bad compressor. obstructed condenser coil, bad starting relay, bad capacitor. among other things.
To check fan motor, set unit to HI Fan Only setting and let it run for a while, check that fan did not loose speed and it is not getting too hot.
If fan is OK, then turn unit to HI Cool 60-65 degrees and see what happens. Hear if compressor kicked in or if just made a humming noise and stopped. if this happens, replace capacitor.
Keep me posted!! Rate this post!!

Fan will not run on high. Compressor runs fine but the fan will not run on high. Works fine on low and med.

It's the mode switch contactors for the high setting just overview the wiring of the high cool or high fan contactors if it's not there check all leads for the high fan or high cool circuitry.

Penguin model 610012-001a/c compressor won't start

I would check to make sure that the control is sending the "cool" signal to the control unit. LO on the room temp display usually means that the fan speed is set to low. Is LO and Auto showing on the display at the same time. Try resetting the thermostat first. Hold down the Mode and Zone buttons with the tstat off. While holding them down, turn the tstat back on and hold the buttons down until FF appears on the screen. Release the buttons and try the AC.
If this does not work, on the control board is a freeze control switch plug (blue usually). Try unplugging this unit and insert a small jumper wire. If the Compressor comes on and runs then you have a bad freeze control switch. If not, then you should replace the control board.

Hope this helps,

Jeff

My fan motor runs to slow and needs to be speeded up. The fan motor has been changed to a A O Smith. Air conditioner is a Goodman 3 ton.

AO Smith motor speeds are Red low Blue med. And black high. Just unplug from fan switch plug in new speed. Turn power of first. Rus
