I have a Trane AC unit, model HIDE036506A which is about 14 years old. The fan and compressor all of a sudden stopped. I can start the fan by hand but the compressor sounds like it wants to start but...


sounds as if the fan motor is getting hot and going off on internal overload (safety). - which causes the compressor to heat up and also go off.
When this happens the usual 'fix' is to replace the motor although you can try replacing the capacitor.
Since you only see one (capacitor) it's possible it's a 'dual capacitor' which means it's the serving the compressor AND the fan motor.
I would replace the fan motor.
Note: I've seen 'shorted' fan motors before - where the blade just barely turns and you would not want to touch the blade because it will give you an electrical shock.
I would be very careful touching the blade of that motor with the power on.-

Noise from condenser fan. I cleaned the blade and the surronding area. Put some w-d 40 but the noise is still there. It is cold. Should I replace the motor? how hard is it to do? kenmore coldspot...


Go to www.searspartsdirect.com enter your model number and select model number search.

Here you can see a diagram of the unit. The fan motor cost 95 dollars.

It depends on the type of noise it is making.

These motors when failing tend to hum when trying to start which is a sign of a dry bearing.

Rattling sounds or ting ting ting sounds are either a lose fan blade (check the cheap retaining clip on the front of the shaft .. it may have wiggled forward causing the blade to wobble) or a lose mounting screw.

Also I can't tell from the diagram how close the fan is to the drip tray(tray evaporator) These fans not only aid in removing heat from the condenser.. they help evaporate the water in the drip tray.

If you remove the motor.. have it tested before replacing it. At a hundred bucks it's worth a trip to a good electric motor shop.They generally will test it for free.

If you are able to determine the voltage and hook it up out of the cabinet you may save yourself a trip.

Chances are it's a lose mounting screw or that front blade retaining clip.

Best of luck!

I am not getting power to my fuel pump. the truck was running fine until i replaced my spark plugs and wires, then the next morning my truck wouldn't start. I've replaced the fuel pump, filter, relay, fuel...


on a lot of ford products there is a switch that goes from the fuel pump to the inside of one of the bedsides.
what this is, is a shock switch that turns the fuel pump off if it absorbs a hit.
its a really dumb safety feature but its effective.
there is a red button on it that u have to press to make it active again.
sometimes they just trip for no reason.

Sounds like it is overloading and tripping the circuit breaker (that thing that pops up). More than likely when the fan fell down it stopped the blade from turning which caused the motor to overheat, melting the windings insulation which caused them to short out which causes the circuit breaker to trip.

Sorry, you are going to have to get a new motor to go with the new lid.........

Pond pump trips circuit breaker


The circuit breaker trips because there is an electrical short in the pump itself or in the wire feeding the pump. A cause of this could be a bare wire, or a crack in a wire. Remove the pump and put it in a five gallon pail of water and test it. If it still trips the breaker you will know the problem is in the pump or the cord to the pump.
