How to repair and replace a thermocouple in the Furnace? What is Thermocouple? The thermocouple is a necessary part of the furnace in terms of security. A thermocouple is a small, continually burning flame. It is commonly used in the gas furnace with a standing pilot. The thermocouple's top is situated in the flame to ensure that the tip is always warm.  When the pilot flame goes out, the thermocouple automatically shuts off the gas valve in the furnace. That's why your thermocouple must be in good condition. If it failed, then replace it with new thermocouple replacement parts. What distinguishes a thermocouple from a flame sensor? Thermocouples are commonly found in older furnaces. However, new installations are now mandated to use electronic fuel injection furnaces.  Flame sensors use electronic integrations instead of standing pilot lights, and thermocouples use standing pilot lights. Flame sensors ignite only when needed. Metal probes and brackets are used in...

How do you find a damaged control board and Replace it in the Furnace? What is a furnace control board? Control boards are specially designed for controlling furnaces and heating units in HVAC systems. It is the brain of the furnace because the control board controls all parts of the furnace. In a direct wire-for-wire replacement, they may Replace OEM control boards. Use heat units and components that are compatible. What are the common reasons for failing the control board? The circuit board is near the expiry date. Failed blower motor. Fuse wiring is not compatible. Contamination with chemicals. Circuit-board failed connections. Filters are clogged. Relays and controls are stuck. The buildup of dirt, dust, small particles, and debris in the unit. Heat, condensation, and wetness in excess. Because of a faulty starting capacitor. There are spikes and troughs in power. Uniform electricity. The board or its connections...

Common problems and Replacement process of ignition module in the furnace What is an Ignition Module in a Furnace? An ignition module is an electronic ignition system. It is used to make contact circuit breakers for the coil. The ignition module is mostly used in modern gas furnaces instead of old ones. Pilot lights are used in an old gas furnace. Silicon nitride or silicon carbide is used to make the ignition module. How does the ignition module work in a furnace?  In a gas furnace, when the thermostat turns on, the ignitor produces a spark that "ignites" the fuel connected to your furnace. It is a necessary component to release the fire from the spark plugs. For the motor to work correctly, every spark plug must burn at precisely the time. The ignition module takes signals to decide when the spark plugs should be fired.  How to test if the ignition module is working or not? Connect the negative terminal of the battery on the ignition coil to the earth line from the ...

How to Clean Furnace Flame Sensor What is a furnace flame sensor?  Flame is the safety equipment in the furnace system. Flame detects the temperature and sends data to the furnace burner. If the flame doesn't work properly and sends data to the furnace, then the flame sensors shut off the furnace.  More important points about furnace flame sensors:  Flame sensors are also known as heat sensors The flame sensor is more efficient than a carbon monoxide detector The flame sensor is made with a thin metallic rod Clean your furnace flame sensor once a month regularly Flame sensor location in your gas furnace: Every manufacturer's furnace design is unique. Open the panel of the furnace Find out single wired attached with porcelain  That is the location of the flame sensor in your home furnace Why do flame sensors become dirty? Carbon monoxide builds a layer on the flame sensor. That is why flame sensors become dirty. And sensors do not detect correct...

Types, Problems, Troubleshooting of Furnace Pressure Switch What is the furnace? The furnace is a heat-generating device using combustion technology. We can categorize furnaces into the following types: natural gas, oil, and electric. In the furnace's burner, heat is produced by burning propane or natural gas. It becomes hot after passing through a heat exchanger with the heat generated. Warm air is forced over the heat exchanger from the ducting of the house. Natural gas: Natural gas furnaces use a combination of hydrogen and carbon gases as the primary sources of fuel. It is a highly energy-efficient furnace.  Oil: Oil furnaces use alternatives for natural gas, where natural gas resources are limited. It is not efficient as natural gas. Safe to use and less expensive. Electric: The electric furnace is safer to use compared to gas and oil furnaces. It is also safe for the environment because it does not emit carbon monoxide. What is a Pressure Switch? The pressure switch...
