The blower fan on this model has reverse threads where it screws onto the motor shaft. At the small space between the motor and the rear wall of dryer you will see that the blower wheel has a square neck that will allow you to hold it stationary with a large crescent wrench. while holding the blower grip the pulley on the front of the motor with another wrench (or channel locks) and turn the motor shaft clockwise to break the blower loose. Sometimes a quick motion is better to free it as it may be on the motor threads pretty tight.
Good luck on this!

Intertherm MGHA-070ABFC-05 will not run/cool


Multiple problems. Eliminate thermostat first. Remove face from wall and turn on breaker. If fan still runs you have a bad board or bad relay. If fan outside is running compressor should be too. These operate on same contactor. Verify you are getting 24 volts to coil side of contactor. If odf stops working and contactor remains pulled in you have a bad motor. If odf motor stops working the compressor will shut off due to overheating.

Why does my Ruud HVAC ventilation fan run constantly?


The two relays on the control board are for the heat (low speed) and for the cool (high speed) cycles. You should be able to determine which speed is sticking in by removing one at a time the heat speed wire and the cool speed wire. At any rate the circuit board will need to be replaced to correctly resolve the issue. If you have a 'clamp on ammeter' you could determine which wire to the motor (in addition to common) is remaining in the circuit. My concern is if the cool speed is the relay that is stuck on the motor may overheat when the heat relay closes. The circuit board reverses the position of the contacts in the two relays when in one mode or the other and stuck relay contact will not allow the opposite speed to de-energize. When you said the motor sounded like it was running 'correctly' when the cool speed was removed leads me to believe you have two winding energized due to the stuck relay and motor overheating and eventual failure is bound to occur. There is an internal winding thermostat that shuts power off when the motor overheats, but only so many times then it will remain open necessitating motor replacement.

You can definately change around the motor speeds, but you cannot use the cool RELAY for heat and vice versa as they are controlled by the board logic and inputs.

Of course there are always NEW products coming on the market that operate differently than the old systems.

My Vornado VH2 heater stops heating several moments after switching on. The fan runs but no heat. The heating elements never get hot but all the wiring appears to be firmly in place. The tilt shutoff...


A big problem with these heaters ans well as others is the motor driving the fan. The bearings get stiff from dirt and do not spin fast enough activating the over temp device of the heating element. Check the motor out by placing the unit in fan mode them pull the plug or turn off looking at the fan to see how many revolutions is makes with no power applied. It should rotate like five times or more indicating freeness. If it hals to a stop immediately after power is removed the motor bearings are tight.
If your handy you take apart and oil the shafts using 3inone motor lube. Clean the motor of dust and dirt drop a few drops on the shafts near the bearings then work it in by hand rotating the blades. Do this a few times reassemble then ler ripp!!!

The fan on the bryant high efficient heat pump moves very slow or not at all


Hi, this is a 3 ton unit. It may or may not have a variable speed fan. You are saying it turns very slow or just stops. I believe you either have a problem with the run capacitor, or you are loosing this motor. They are putting variable speed blower motors on some units now, but if you are talking about your condenser fan motor, it may have a head pressure control to speed up this motor when the ambient temperature is higher and slower when cooler, but to stop when running indicates a motor or run capacitor problem. Check the cap. for oil leaks, swollen and deformed, burned terminals. If you find this, replace it. Remove the fan guard and carefully with the power off after it has ran for a while touch to see how hot the body of the motor is. If it is to hot to touch, you are loosing this motor. If you have a clamp around amp probe or know someone who may, you can look at the data plate to see what this motor should be drawing as far as amps and compare your readings to this. You will know for sure doing it this way.

Fan motor won't stop running


Good chance the relay has gone bad and needs to be replaced. The heat from the current has damaged the relay and is seized to the close loop position causing the fan to keep running, Just remove the relay so the fan will not drain the battery over night, Good luck friend.

Amana Cooling Condensing Unit fan stops spinning after 15 mins


Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

The fan in the airhandler wont shut off.


The fan is controlled by a blower timer board located inside the air handler, or on older units it has a relay called (of all things) a blower relay. If these items were at fault I doubt removing the thermostat would cause the blower to go off. if bad causing this problem the blower would continue to run even with thermostat removed.

But it is also controlled by the thermostat.

You mentioned that if you remove the thermostat it cuts off. There are 2 switches on most thermostats.
1 has Cool, Off, Heat, and Emergency Heat (on a heat pump stat)
2 The other switch has On and auto (it is for the fan motor only)

I believe because it stops when you remove the thermostat that the switch on the fan is set to on possibly. It should be on auto-matic. This way the fan motor only come on with cooling or heating. If in the on it stays on all the time. If this is the case just switch to AUTO.

Or the thermostat may be wired wrong. The G terminal is where the fan motor gets instructions from the thermostat. Make sure its on G at the stat and the correct wire at the blower coil is being used for the corresponding wire going from the stat to the blower for G. Don't confues G for green it could be any color. The terminals are not for color but it makes more sence to make them color - letter identified. On the other end soemtimes the wires are not colored the same so look carefully.

Also a whisker of a thermostat wire could be touching inside the thermostat and causeing the motor to run 100%. Look carefully at this and see if it has too long of thermostat wires stickinhg on out under the screws to where they may tough other things.

If neither things stop or show the problem and it deffinately stops when thermostat is removed the thermostat is most likely bad.

If this helps you 1 way to make the repairs your\self or helps you realize you need a technician please rate mne as high as you can.
