Operating with natural or propane gas, your Coleman furnace blower's electric fan draws cool air in, heats the air, and then propels the warm air through ducts to distribute heat throughout your home. The air returns to the furnace as cooler air. The furnace burner looks like a row of tubes in which the correct amount of air and fuel mix in order to burn effectively. Your Coleman furnace also has two high temperature limit switches to protect it from overheating by turning off the power to the ignition controlling the gas valve. You must reset the Coleman furnace switch to get your furnace operating again. (See Reference 4 #3 & #5, and Reference 5)
M/F Turn the Coleman furnace system switch to the "Off" position on the electric service panel.
M/F Locate the manual reset switch near the left side of your furnace blower. Your Coleman furnace has an upper limit switch for manual reset and a lower limit switch for automatic reset.
M/F Press the reset button, which you will find in the middle of the limit switch. Use this manual reset button when the furnace burner will not operate. (See Reference 1 pg 4 "The Furnace Controls and their Function/Important" & Reference 4 # 3)
M/F Arrange for your Coleman furnace to be professionally inspected and serviced every other year. The inspection reveals wear and tear, such as rust, frayed wires and leaks. A professional will also inspect the ducts, blower, fuel line and every part of your furnace. Inspect the furnace yourself at least every 90 days. (See Reference 1 and Reference 2 pg 6 "Periodic Inspection")
M/F As of November 15, 2004, the U.S. Consumer Product Safety Commission (CPSC) and the Unitary Products Group (UPG) of York International Corp. issued a recall of furnaces, including Coleman and Coleman Evcon furnaces. If you purchased one of these furnaces between 1995 and 2000, stop using the heating function.
