Why does my wall heater keep turning off?

The heater won't operate properly if the pilot flickers, is too weak or goes out, and the cause could also be blockages in the pilot tube. Another cause of a weak pilot is a faulty thermocouple. It's a heat sensor placed next to the pilot flame that signals the gas valve to stay open when the flame is burning.

Why does my furnace turn on when the thermostat is off?

The system uses a “temperature probe” to detect temperature changes inside the heat exchanger (see image below) and turns your blower on and off in response. So if your furnace blower is turning on and off when the furnace isn't in a heat cycle, it usually means the fan limit switch is defective.

Why does my furnace turn off after a few minutes?

A common reason a furnace short cycles is because the heat exchanger, the part that heats your air, is getting too hot due to a lack of airflow. Once the heat exchanger overheats, it trips the high limit switch, which shuts the furnace down to protect it.
