The furnace not working can be pretty inconvenient since your home is cold. It’s even more aggravating when you can hear the heater turning on and preparing to emit toasty hot air… But nothing occurs after that. Most contemporary model furnaces are built for long-term durability (assuming proper maintenance) and are one of the most expensive and necessary appliances in practically every home.

Reasons for your gas furnace not working might be complex or straightforward. While you should generally leave complicated problems like thermocouples, wiring, heat exchangers, and blower motors to a competent expert, you should check a few things before calling a certified HVAC contractor for furnace repair assistance. Before attempting to repair a broken furnace that won’t start, determine the type of furnace you have. Forced air and gas (propane, fuel oil, and natural gas) furnaces are the most frequent in this area.

In such cases, you must locate a skilled contractor who can assist you in adequately replacing the damaged spark electrode.

Pressure switch failure

Another possibility for your water pressure igniter of the furnace not working is a faulty pressure switch. The pressure switch’s job is to close when the water heater system has enough airflow. Closing the pressure switch instructs the control board to resume the ignition operation. However, if the system fails, it will stall, which may result in the water heater not igniting.

In most circumstances, a failed pressure switch is caused by faulty parts or a bad connection. All of these problems may be resolved if you hire the correct contractor to manage the system. The specialist will figure out the cause of your pressure switch malfunctioning and fix it.

The pilot isn’t turning on

The pilot in the water heater system’s job is to light the gas burner on the water heater. As a result, if the pilot does not ignite, the water heater will not heat.

As a result, the water heater igniter will not spark. One of the most prevalent causes of the pilot, not lighting is the accumulation of carbon deposits surrounding it. When the buildup becomes excessive, a limit is imposed. If the problem is a limited pilot light, you may quickly resolve it by cleaning the accumulation with a sharp brush or compressed air.
