To test the blower motor on its own, you will need a 12V power supply like an RV or car battery. Next, place the test leads to join the positive and negative wires of the blower motor to the positive and negative terminals of the battery. The fan should start immediately. Blower motor...
GWT (Glow Wire Test) or end product burning wire test, used to test the flame resistance of finished relays (test temperature must meet 750℃). GWIT (Glow Wire Ignition Temperature) is used to test the ignition of the material (the test temperature should meet 775℃). GWFI (Glow Wire F...
When you take the cover off the furnace, do a simple test by turning up the thermostat to call for heat and watching the flames. You want to make sure the flames in all the burners are the same size; if one of the flames is smaller than the others, buildup on the burner has gotte...
A flame sensor performs the same function as thethermocoupleon a gas water heater with a standing pilot. A standing pilot is one that is always burning, and the job of a thermocouple is to shut off the gas if the pilot goes out. A gas furnace has an electronic igniter instead of a s...
As the flame burns, it heats up the metal in the surrounding tubing. When the tubing becomes hot, it heats the propane flowing through it. This changes the propane from a liquid to a gas, before it is ignited. This gas makes for a more powerful flame and more efficient fuel consumption...
Poor air quality and hazards posed by asphyxiates and toxic gases are some of the most common hazards faced in a confined space. Learn how to identify them in time.
Should the O2 sensor be replaced when the sensor light comes on in your car? Probably not, but you should test it to make sure it is alive and well. This assumes that the light you see is simply an emissions service reminder light and not a failure light. A reminder light ...
The heat capacity of the fireplace is related to its weight/material/temperature; Fuel consumption, burning 10 kilos versus 30 kilos, is definitely different; The insulation of the house, air leakage and double-layer insulating glass are not the same; Optimize that, and you get a warm night....
This type of control board is found in older furnaces and is used to control the flame sensor, igniter, and gas valve. It’s less efficient than an integrated furnace control board. However, it is much cheaper and easier to install. ...
Soapy water is the most common and easy method used on the stove and other places to test for leaks and tell where they are by applying it around pipes and looking for visible bubbles. Visible bobbles indicate air is leaving the space. ...
