Question about Rheem 4 Ton Air Handler - RHLLHM4821JA
Had a power outage last night and the unit turns on outside and the coils in the air handler freeze so its just the inside fan that does not kick on...Is their a way to trouble shoot this?
Check for fan operation by turning the fan control at the thermostat to "on". If the fan blows, it works. If not, check a circuit breaker or fuse.
If the fan blows when forcing it on with the thermostat but not in automatic, check the fan control circuit in the air handler. Danger: high voltage, beware! There should be a system wiring diagram inside the air handler somewhere.
