What is what to do when furnace stops working?

Here's what to do when your furnace stops working:

  1. Check the Thermostat: Make sure your [https://www.wikiwhat.page/kavramlar/thermostat%20setting](thermostat setting) is correct. Is it set to "heat" and is the temperature set high enough to trigger the furnace? Batteries might need replacing.

  2. Check the Power: Ensure the [https://www.wikiwhat.page/kavramlar/furnace%20power%20switch](furnace power switch) is turned on. It's often located on the furnace itself or nearby. Also, check your circuit breaker box for a tripped breaker related to the furnace. Reset it if needed.

  3. Check the Gas Supply: If you have a gas furnace, confirm that the [https://www.wikiwhat.page/kavramlar/gas%20valve](gas valve) is open. It's usually a lever parallel to the gas pipe when open.

  4. Check the Filter: A dirty [https://www.wikiwhat.page/kavramlar/furnace%20filter](furnace filter) can restrict airflow and cause the furnace to overheat and shut down. Replace the filter if it's dirty.

  5. Check the Pilot Light (if applicable): Some older furnaces have a pilot light that needs to be lit. Follow the manufacturer's instructions to relight it. Newer furnaces have electronic ignition and don't have a pilot light.

  6. Wait and Reset: After making these checks, turn the furnace off at the breaker for a few minutes, then turn it back on. This might reset the system.

  7. Call a Professional: If none of the above steps work, it's time to call a qualified [https://www.wikiwhat.page/kavramlar/hvac%20technician](HVAC technician). There could be a more serious problem, such as a faulty motor, gas valve, or control board. Do not attempt to repair gas-related issues yourself.
