Question about Heating & Cooling
Have a problem with my furnace, and I hope you can help me. I switch the tstat to call for heat, and the following is what I get ..... 1. The Combustion blower starts. 2. Then I hear a '' CLICK '' 3. There is a long quite moment. 4. The another '' CLICK. '' 5 Finally the main blower turns on, and all we have is cold blowing air. NO HEAT. I never see the Igniters glow, and I only smell a hint of gas. MAKE : LENNOX MODEL:G26Q3-75-1 S/N 5894L37210
Sounds like the ignitor is bad. there shoule be a 2 wire plug going to it. after the inducer motor starts, you can check the voltage at the 2 wire plug located under the burners. you can unpug it to check voltage or you can probe the back side of the plug with a volt meter. if you are getting 120v but it is not glowing, it is bad. you can also ohm it out while it is off.
