Why Is My Furnace in Cabot, AR, Not Kicking On?

When the furnace in your home in Cabot, AR, doesn’t kick on, it either has a technical or mechanical issue. This guide breaks down the most common reasons why a furnace fails to power up.

Thermostat Problem

Every time you turn on your furnace, its thermostat makes the command. If the thermostat malfunctions, the furnace will never start its heating cycle.

In most cases, an incorrect thermostat setting will trigger a thermostat problem, so you may want to check the setting on the thermostat to ensure that it’s in “Heat” mode. Also, look at the temperature on the thermostat. If it’s lower than the current temperature in your home, the heating system won’t kick on until after you adjust the thermostat to a higher setting.

Blown Fuse

A furnace needs gas and or electricity to heat a house. It uses gas to create heat, and it blasts the hot air using electricity. If your heating system blows a fuse or circuit breaker, it won’t be able to circulate air.

When your system has a blown fuse or circuit breaker, you can restore power by checking the circuit breaker panel. Inside this panel, locate the switch for the heating system and switch it to the “On” position.

No Heat Source

Many older furnaces have a pilot light. If this light goes out, the heating system won’t ignite correctly.

Gas Valve Issue

There are many safety precautions for a furnace. Some technicians may turn off a heating system’s gas valve in the summer as a safety precaution. If you think that your heating system isn’t receiving gas, find the gas valve and rotate it to reactivate the gas supply.

Furnace Performance Problems

As a furnace heats a home, proper airflow influences its overall performance level and the air quality. If a heating system has an airflow issue, it will fail to start its cycle. You can correct and prevent airflow problems by maintaining a clean filter.

In some cases, a furnace that doesn’t power up will require professional maintenance or repairs. If you need professional service for your furnace in Cabot, AR, contact us at Freyaldenhoven Heating and Cooling.
