The air conditioning in my Intertherm Central Electric furnace is not blowing cool air.
Model FEHB-017HA. It is set on Auto and the two switches on the bottom right are set to on and off. I really don't know what the right one is for but the left one seems to switch the blower on and off. The thermostat on the wall seems to be working as the furnace will kick on when the temp goes up past 22 degrees where it is set.

Is the condensing unit outside running when the t-stat calls for cooling? One switch on the t-stat is the fan switch and just turns the fan on continuously. I don't know what the other one is. DrTom4444

One switch is the fan switch to turn on fan continuously and the other is probably the emergency heat switch which would not affect the cooling mode. You have it set to bring on the compressor at 72°F, so apparently the compressor is not coming on for some reason. It could be anything like a tripped breaker that supplies the outside unit. It would be a double breaker rated between 20-40 amps. Some units also have reset buttons low on the rear of the unit. The button is usually red and will trip when the coils get too dirty outside. You need a meter to test the circuits outside and determine whether the contactor is getting 24 volts to the coil. If not another safety could be tripped or there could be another reason. DrTom4444
