  • First, check the power of the thermostat.
  • Use a multimeter to measure the power by touching its probes on the thermostat.
  • Make sure no breaker is tripped, or the power is dissipated.
  • Check or set the thermostat in the heating mode.
  • If the thermostat has been reset, set the temperature to the required level.
  • The temperature should be set more than the temperature outside.
  • Turn the machine on and see if it works.
