Air conditioner

[Diesel75]

Yesterday it worked, today it only puts out warm air. Is there anything I can do to fix it??

If it is a heat pump, there could be 2 trouble spots:

• your start capacitor (smaller one) and PRCT (motor start device) are bad and need to be replaced. NOTE! They should only be replaced with ones of identical specifications.

• If a heat pump, the reversing valve solenoid is bad, resulting in your A/C unit being stuck in heat pump mode (ALL heat pump units are in heat pump mode by default. The reversing valve solenoid must be energized by the control board to function as an air conditioner)

Notice a slight burning smell?.......... probably your capacitor.

Be sure to have the A/C breaker OFF when testing the caps.

BTW: they are located on the upper unit under the shroud on the curb side of the A/C unit. Remove the rectangular plate you will find there and the caps are right behind it.

did you check for low AC voltage?

Only thread I could find on AC. I have a FC 25'. I have noticed during this heat wave that the central area is comfortable but the back bedroom area is not getting enough cool air. Could use a duct to the back.
