What Are Some Common Reasons My Heat Might Not Be Working?

If your heater isn’t working in California, it could be caused by several common issues. Even though California isn’t known for extreme cold, your heating system still needs to be in good working condition when you need it, especially for those chilly nights.

Here are some of the most common reasons your heat might not be working:

  • Thermostat Issues: The thermostat may be set incorrectly, have dead batteries, or be malfunctioning. Make sure it’s set to heat mode, and your desired temperature is above the current room temperature.
  • Dirty or Clogged Air Filters: A blocked filter can restrict airflow, making it hard for your system to deliver warm air or even causing it to shut down as a safety precaution.
  • Tripped Circuit Breaker or Blown Fuse: If the furnace isn’t receiving power, it won’t turn on. Check your electrical panel for any tripped breakers.
  • Pilot Light or Ignition Problems: Gas furnaces rely on a pilot light or electronic ignition. If that component fails, the system won’t be able to heat your space.
  • Faulty Blower Motor: If the blower motor isn’t working, warm air won’t be distributed through your vents.
  • Dirty Burners or Heat Exchanger: If these components are clogged or malfunctioning, your system may not produce enough heat or may shut off as a safety measure.
