Common Gas Furnace Repairs and Failure Rates
Introduction
In regions like Yelm, Tumwater, Lacey, Olympia, Rainier, Roy, Spanaway, Centralia, and Chehalis, gas furnaces are a popular choice for home heating. Understanding the most common issues and their frequency can help homeowners anticipate maintenance needs. Here are key parts prone to failure in gas furnaces.
1. Filters (Failure Rate: 80%)
Filters are crucial in maintaining air quality and protecting the furnace from dust and debris. Neglecting to replace clogged and dirty filters can lead to decreased airflow, reduced efficiency, and even overheating of the furnace.
2. Flame Sensor (Failure Rate: 50%)
The flame sensor plays a vital role in furnace safety by detecting whether the flame is lit. If it fails or gets dirty, the furnace might shut down as a safety precaution, leading to no heat production.
3. Pressure Port on Inducer (Failure Rate: 50%)
The inducer motor helps maintain the correct pressure in the furnace’s venting system. Issues with the pressure port can lead to improper furnace operation or even a shutdown.
4. Ignitor (Failure Rate: 50%)
The ignitor is responsible for lighting the gas in the furnace. A failing ignitor is a common issue and can prevent the furnace from starting up.
5. Limit Switch for Fan (Failure Rate: 30%)
The fan limit switch regulates when the blower fan turns on and off. A malfunctioning switch can lead to improper temperature regulation and, in some cases, an overheated furnace.
6. Control Board (Failure Rate: 30%)
The furnace’s control board is the central hub for electrical operations. A malfunctioning control board can lead to various issues, including problems with the thermostat, blower motor, or other components.
7. Blower Motor and Capacitor (Failure Rate: 30%)
The blower motor and its capacitor are essential for circulating air throughout the home. Failures in these components can result in poor air circulation and inconsistent heating.
