How to troubleshoot your Friedrich air handler when it won't run

Check for power and reset the house circuit breaker for the air handler if it's tripped. If the air handler is getting power, check the thermostat settings and adjust the settings if necessary.

Check for water dripping from beneath the air handler. If water if dripping from the bottom of the air handler, then the condensate drain hose is likely clogged. A switch in the air handler shuts off the unit when the drain hose clogs and water backs up into the evaporator. Unclog the drain hose and the switch should reset so the air handler will run.

If these tips don't help, then a bad blower motor or a failed control board could be preventing the air handler from running.

What to do when your Friedrich air handler won't move air

• Check the air filter. A clogged air filter won't let any air go through the air handler. Replace the air filter if it's dirty.
• Check the vent grill. A blocked or dirty return air vent grill can inhibit air flow through the air handler. Move any items stacked in front of the return vent grill. Clean the vent grill if it's dirty.
• Check the house circuit breaker. If the air handler blower motor isn't running at all, reset the house circuit breaker for the hair handler. If the motor still doesn't run, you'll likely need to have a service technician examine and repair the air handler.
