Go to electric motor shop . take oem capacitor. replace with exact replacement. rule on capacitors is uf or mf rating must be exactly the same. voltage can be higher. for instance if you have a 370 cap you can replace it with a 440 cap but never the reverse. to pull a bad 120 cap and replace it with a 230 cap is ok. but to pull a 440 cap and replace it with a 230 cap is a no no.cap rating must remain the same . volt rating can be higher but not lower.if motor still turns in reverse look at the reversing leads. see wiring diagram on the side of the motor. most replacement motors can run cw or ccw. by switching the reversing leads you can effect direction. usually wired up orange to orange and purple to purple. switch org to pur and pur to org and motor runs opposite direction. be sure you have a new correct cap for the new motor. every new motor should have a new cap and they are different usually.one motor might be a 5 mf cap and the new motor might require a 15 cap! be sure power is off and you check it three ways. looks off, checks off with a meter, and is off when shorted with a screwdriver.good luck

Fi have a older furnace that operates like this. main burners will come on then the blower turns on and furnace continues to heat untill it shuts down on the high limit. there is no blockage on the cold...


Maybe there is a blockage in the air conditioning coil above the furnace? This happens when people have pets, or dont use filters. Single phase 120-240 volt motors won't run backwards if you reverse the wiring that's dc or three phase, you have to check the rotation of the wheel, the right rotation is usually marked on the blower case. Some motors will allow you to change the rotation but you have to check the wiring diagram. Also use new capacitors when they go bad the motor can run backward. God luck

Tip

A/c shuts off within 5 seconds whenever operate by remote.


Service your unit periodically for reduced breakdown. Due to defective indoor room sensor and coil sensor, it shuts off within 5 seconds whenever you switch on. Replace it. If indoor fan motor mechanism locked also same problem araised. Rotate manually blower wheel. If hard, it needs bearing replacement or fan capacitor or motor itself.

Air conditioner unit is working but the inside fan is not cutting on.


Check your circuit breaker for the indoor fan. If that is ok try turning the indoor fan by hand to see if it rotates freely. If it doesn't it probably needs to be replaced. If that's ok then check the capacitor for the indoor fan. It is probably attached to the fan. You can check it with a multimeter with the capacitor check function or take it to a heating and air supply and they can check it. Also check the fan motor windings. Connect one lead of an ohmmeter to the common leg and the other to the start leg. Check the reading remove the lead from the start leg and connect it to the run leg and see what it reads. Common to start should be higher than common to run. If either indicates an open winding then the motor needs to be replace. Some motors have more than one speed. High speed is usually used for A/C.

My indoor blower is not working it blinks 8 times


This alarm state is a CH08 alarm. Which indicates that the indoor unit fan motor has a locked rotor. Solution is to check the indoor fan capacitor and replace or test the windings of the indoor fan motor. Note: the indoor fan motor is a BLDC fan motor and can not be replaced with any other motor. It runs of a voltage regulated frequency.

Turn off unit supply and check the blower wheel inside the indoor unit by rotating it manually by your finger if the blower wheel rotates freely then there is something wrong with your fan motor or fan motor capacitor. But if the blower wheel is not rotating freely try to check the fan motor for lubrication or some bushing dried of and no oil
