Gas Furnace Thermal Sensor
Gas Furnace Thermal Sensor. If the flame sensor is defective, it might fail to detect a flame. A significant rise in temperature indicates that the above condition has occurred.
It is a safety device that shuts off the gas if the pilot light goes out or the electric igniter fails. Flame sensors vary in size (2 to 4 inches) and shape (see examples below). The short answer is it regulates the fuel or gas inside a furnace to prevent major malfunctions, such as an explosion.
The Furnace Flame Sensor Helps Prevent Explosions That Could Occur If Gas Were Allowed To Continue To Flow Into The Home As Well As Carbon Monoxide Poisoning Of Those Inside The Home.
On a gas furnace, they provide an incredible safety feature when they are working right. Skipping the cleaning part, proceed by mounting the new furnace flame sensor by doing the above steps now in reverse. Not all furnaces have a flame sensor, but if your furnace has one, it will be mounted close to the burner with the metal rod positioned in the flame.
If The Flame Sensor Can't Sense The Flame Because It's Too Dirty, The Furnace May Shut Itself Off.
Shut off the gas valve and power for the furnace. Check if the belt is not broken or needs tightening. Which you can access the thermostats.
The Advantages Of A Thermal Mass Flow Sensor For Industrial Gas Furnace Applications Include:
Locate the thermocouple next to the pilot light. 4.7 out of 5 stars 5. Direct mass flow measurement independent of pressure and temperature;
[Click To Enlarge] The Thermocouple On Gas Fired Heating Appliances Is Mounted To Sense The Presence Of A Gas Flame Or Gas Pilot Flame.
Our photo (left) shows how you may spot the copper tubing of the thermocouple extending between its sensor at the pilot flame of a gas burning furnace and its connection to the gas control valve. From accidental carbon monoxide poisoning each year and some 50,000 visit the. The flame sensor’s role is to detect whether the ignition process is successful, i.e., whether it produces a healthy flame to facilitate heating.
