Condensor coils froze over and dripped into blower motor. burning smell starts from blower motor and it tripped thermal. replaced motor and capacitor and within 10 seconds this motor starts burning smell.
Check fan cage to make sure it turns freely. Check voltage to IFM make sure it is correct for the application. Make sure the motor turns the fan cage in the correct direction. IFM will have high and low speed make sure when you change from fan on to auto that the motor changes speed. If you have an amp draw meter check to see when running the motor pulls the amp load it is rated for. Recheck all wiring.

A hard start or turbo 2000 will not work if the run capacitor is bad. You will need to contact a ruud supply house or dealer with model and serial to find out the exact match. I have checked my sources and came up empty handed. You could try getting a 35/5 MFD at 440V or a 45/5 MFD at 440V as these are the most common capacitors used in Rheem and Ruud equipment. The key is that you will need to check your amp draws on both motors against the nameplate rating to make sure that you are not over-amping the motor. Also check the nameplates on both of the motors. Most condenser fan motors and some compressors list the capacitor size they require in a somewhat less than conspicious location on the label.

the wire diagram should tell you how. it all depends where wires lead to. be very carefull, capacitors can be dangerous. brown usaully go to fan black usaully goes to common red usaully goes to herm or compressor. it all depends where wires come from
