How to fix an inoperable electric heater in Stulz Compact CWE Air Conditioner?
If the electric heater in your Stulz Air Conditioner is inoperable, start by checking for a tripped circuit breaker and look for a short circuit before resetting it. If the circuit breaker is not the problem, make sure the temperature setpoint isn't too low and increase it if necessary. Also, check if the overheat switch is open due to insufficient air across the heater elements; inspect for dirty filters or obstructions that may reduce airflow, and correct or replace them as needed. Another possible cause is a tripped manual reset overheat safety switch, which you should reset.
