Fan blower Not working
You will want to make sure that the control board is sending power to the fan motor. Also check the capacitor to make sure that it is good. To check the capacitor you will want to discharge the capacitor WJ20X10115 and then do a resistance check to make sure that it shows resistance then drops off. If the capacitor checks ok and the control board WP26X10058 is sending power to the motor then the issue would be with the fan motor WP94X10225.
The evaparator blower motor only runs at low speed. This in fan only, heat and cool modes. The condensor moter runs fine. What would be the problem?
Answer Hi. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. Ohm out the Evap. fan windings. The blk. blu. and the red wires. Ohm 2- at the same time as all 3-different combinations against one another will ohm out the same within 10% tolerance. Ohm one each to motor chassis to make sure they are not shorted. The motor is part # WJ94X10235. Remove the Selector switch connector and ohm out the contacts that all remain closed in the fan high position. Contacts 1 & 4, 5 & 10, and 5 & 6. If any of these are open then replace the switch part # WJ29X10014. The fan capacitor operates the fan high circuit as well . Put the ohm scale on the highest scale after discharging the cap. Discharge carefully by using a needle nose pliers momentarily on the terminals to short the connections. Then meter will show high resistance one way and open the other way(Normally). If not then replace it with part # WJ20X10115. Thank You.
