Reasons Your Furnace Isn’t Turning On

This is an ordeal that can happen for any homeowner. You wake up in the morning to discover your furnace has turned off. You run to the thermostat to switch it back on, only to find out it’s already set to a high temperature. You turn up the dial or press a few buttons and still get nothing. When your furnace stops working, you’re bound to feel a slight sense of panic over what steps to take next. Luckily, technicians recognize that this is a serious problem, and most will do their best to get out to your home and solve the problem as soon as possible.

Here are some of the most common reasons for a lack of heating which lead homeowners scrambling to find a qualified technician for repairs. When you need heating repair in Westlake, OH, trust the experts at Westland Heating and Air Conditioning.

  • Faulty Thermostat: One of the most common reasons a furnace will not turn on is if the thermostat, which communicates to the furnace when the temperature has dropped lower than the desired setting. If the thermostat is broken due to faulty wiring or even just a dirty sensor, your furnace simply cannot turn on. A replacement thermostat is generally your best option.
  • Defective Thermocouple: The thermocouple is a component in older standing gas pilot models that senses how much gas flow is let into the unit. When working properly, it should shut off the unit should the gas flow become too high or too low. This is a safety feature that generally must be replaced if it has stopped working. Alternatively, your furnace may have stopped working due to blockage in the gas line sensed by the thermocouple.
  • Broken Fan Switch: The fan switch basically controls when the blower fan turns on and off. When the fan switch is working correctly, the blower fan should start a couple of minutes after the burner lights turn off. A faulty thermostat will not allow the blower fan to come on, causing no heat to reach your home, and should generally just be replaced.
