Why Doesn’t My Furnace Stay On?

woman in home cold, in need of furnace repairIs your furnace not running correctly? There could be a number of reasons! One of the most common furnace problems is when the furnace burners don’t stay lit. When the furnace burner doesn’t stay lit, it causes the furnace to fire up, heat up for a few minutes, and turn back off before it has time to reach the target temperature.

4 Possible Reasons Your Central NJ Furnace Isn’t Staying On

1. Malfunctioning Thermostat

The thermostat may not be calibrated correctly, meaning the furnace thinks it has reached the desired temperature after running for only a few minutes. To find out, replace the thermostat with a cheap model. If the problem stops, you have pinpointed the problem. If not, return the new thermostat and continue troubleshooting.

2. Bad Thermocouple

This heat sensor installed next to the pilot light serves the important purpose of closing the gas valve if the pilot light goes out so gas doesn’t fill your home. However, a malfunctioning thermocouple may lose the ability to sense heat from the pilot light, causing it to close the gas valve at random. If your furnace doesn’t stay on, check the pilot light. If the pilot light won’t stay lit, a bad thermocouple could be to blame. You may need a professional to take a look and replace the malfunctioning part.

3. Full Condensate Pan

Newer condensing furnaces generate condensate, which drips into a pan and drains away. If the drain line becomes clogged, the pan may begin to fill up. Once the rising liquid hits a sensor, the furnace will automatically shut off to prevent the condensate from spilling over the edge. Check the condensate pan for this problem. If the drain is clogged, insert a straightened wire hanger to clear it out. Sending a bleach mixture or algaecide treatment down the drain may help prevent future clogs.

4. Blower Motor Not Running

When the furnace runs, place your hand over a supply register. If you feel hot air exiting the vent, this means the motor is running like normal. If not, the motor has lost power for some reason and the furnace is switching itself off to prevent the heat exchanger from overheating. The fan relay might be broken or the blower motor belt might be worn out. A furnace repair is your best bet for fixing these problems.
