When furnace turns off blower will continue to run?

no


How do you know if you need to replace your thermostat?

Well, I don't mean to sound snarky, but when it doesn't work anymore! The thermostat, in its most basic form, is just a switch to turn the heater on. If the heater turns on and off like it should, it is OK. If the heater doesn't turn on, or worse yet doesn't turn off, you should look into getting a new one. Some tests you can perform: Heater doesn't turn on? Get at the wires running to the thermostat and touch the two control wires (You will have to look into the furnace documentation if you have more than two wires) together. If the furnace clicks on, it's the thermostat. If it doesn't, it's the furnace. Heater doesn't turn off? When the furnace is running disconnect one of the control wires. If the furnace shuts off it's the thermostat. If it doesn't, it's the furnace.

Why is my blower motor rear defroster and AC controls not working all of a sudden Not even the LED lights light up on a 1998 Cavalier Help The blower motor was starting to fail as I had to tap it .?

Ok..I figured it out. Turns out the rear defroster is the problem. When I unplugged it from the back windshield, blower/heater works great!! So...to all those out there..if your blower motor blows fuses...check the blower motor first...then the HVAC and heater fuses, then rear defroster if you have a cavalier!


How is oil used to form electricity?

Oil is burned in a furnace as fuel to produce heat. Running through the furnace is a series of pipes containing water. The water turns to steam with the heat - which is then used to turn turbines. The turbines generate the electricity.
