There are multiple reasons why the heater may not start. Here are the most likely reasons:
One of the circuit breakers or fuses in your location may be tripped. (240 vac = 2 – 120 vac circuits) check the breaker panel to rest the breaker(s) (2 breakers are used for the 240 vac heaters).
The plug or power supply outlet connection may be defective or bad. Try another plug or check the breaker panel to reset the breaker(s) or replace a fuse.
The thermostat may be set too low or is defective. Or the wiring to the remote thermostat is loose or bad. Check connections at both ends of the wiring from heater to remote thermostat. Turn the thermostat up to a higher setting, or replace the thermostat.
The high limit thermal overload switch may have been tripped. Turn off the heater and wait for it to cool down before turning it back on.
