What is it and what is in it? Due to the aforementioned cold weather, it became apparent that using the heat pump was not going to cut it. When we set the thermostat for furnace the blower would come on, run for about 30 seconds and turn off. No heat and did not hear the pilot light kick on. Bob (poor Bob, thank you, Hon) had to go outside to disassemble the furnace. This is a mud-dauber wasp nest inside our furnace. Pesky little buggers. A couple dormant, half-frozen wasps inside gave him no problems when they were summarily dislodged and removed. Did this solve our heat issues? Uh, no. Still no heat. The manufacturers really want to discourage owners from doing their own repairs so he couldn't get inside the furnace. The cold air return was essentially clean, a couple clumps and dust. Repair technician managed to get into it and found a small clump of dog hairs blocking a metal tab(sail switch) from making contact which completed the circuit for the pilot light ignition. Problem solved. |
