My 4 year old Ruud home a/c compressor stopped working. inside fan blows but compressor won't turn on...what can I do prior to calling the gas company who installed the unit...


Ruud parts warranty from factory is 5 years, the capacitor has possible gone out, it will be in the contol compartment on the out side unit and is a dual run capacitor that controls the compressor and fan motor. Recommend if capacitor is bad to replace entire capacitor. As Stated above the parts are under warranty if under five years old. To verify age the date code is in the serial number after the "F" **** week/year of manufacture. Also outside unit has independent power supply so check fuses if any and circuit breaker.

I have a Portable Windchaser Air Conditioner and the back filter looks very dusty. Should I replace or clean the filter? There doesn't seem to be a way to remove it without disassembling it. Thanks...


these filters can usually be removed and cleaned by carefully sliding it upwards. Some units they just unclip, pop off with a sligh force. However removing the filter will only expose the evaporator, it is MUCH recommended to remove the entire back cover of the unit to gain access to the condenser and clean both of the radiators.

I have a RUUD central air conditioning system, model NBHC-18J20SFA. The cooling function is not working. The fan on the outdoor unit is not working. When switching to COOL, the compressor works for a few...


sounds like the outdoor fan motor and/or capacitor needs replaced. The compressor will run for a short time because the fan is not pulling the heat out of the system, it can cause damage to the compressor if the fan is not repaired, Ruud used a 3uf capacitor rating for the outdoor fan motor, if the motor has been changed make sure the proper capacitor is also changed for the new motor rating.

No cool air, squirrel cage motor is humming, not running on its own. Cold line is freezing up at connection to outside unit and inside unit. Coils on the inside unit are freezing. This is an older unit...


Take the whole blower housing out. Remove the blower motor get the H/P, RPM and voltage they sell these motors that are universal they are called rescue motors they work for everything. Also make sure to replace the capacitor on the blower motor when you do the work. If this helps please rate me and do a testimonial.

Outdoor fan will stop running and compressor overheats and shuts off. it wont come back on til u reset it at the thermostat. the outdoor unit has a new compressor and fan motor.


I realize the outdoor unit has a new compressor and fan motor - therefore - both those components should be ok - however - the fan motor 'should not' be going off - and the fact that it is going off is what is causing your compressor to overheat and shut off.
The reason the fan motor is going off is - it is bad (breaking down electrically) and is going off on the internal overload. If this is the case (a) the motor needs to be replaced or (b) it's possible that the fan capacitor needs replacing; but fan capacitors generally do not cause much problem, and when they do go bad they usually develop an obvious (to the eyes) bulge. If the capacitor has a bulge in it - I would surely change it out -and probably would (as a shot in the dark) anyway - since they are relatively cheap ($10-$15).
In your complaint you say that "the outdoor fan will stop running and compressor overheats and shuts off." If it happens 'exactly' that way then I'm betting your problem will be that the fan motor is defective as mentioned above, with an outside chance of the capacitor being defective, in which case if it isn't the capacitor - you will need a new fan motor. Note: outside fan motors are notorious for being fickle and it would not surprise me in the least to find a fairly new outside motor that is defective. I would check and see if you had any warranty on it.
All that being said - it is also possible that your outside unit has a 'high pressure cut-out switch,' although most units don't have them anymore, these days. However, if you have such a switch - it is possible (very likely) that it is shutting off the AC. Note: a high pressure cut-out switch will 'shut the entire outside unit off,' not just the fan motor. If that is what is happening then there's a good chance you have such a switch.
If it is happening that way, (the entire outside unit stops) then I would try 'washing the outside coil' really, really good and see if it will run ok afterwards.
Note: outside coils are sometimes difficult to get clean - sometimes requiring you to disassemble to some degree in order to make sure you get them clean.
Always, Always turn all power (including inside thermostat) OFF when washing the outside coil.
