Hello All Brothers, we really, really need your help. Our family live without heater almost a week. We both lost our jobs that is why we must wait until today.
Here is the problem: Based on the diagnostic codes, 1st LED flashes, 2nd LED is On => Primary or secondary limit switches open.
Here is what we did: We first took out the primary switch and bypassed it by connecting 2 wires together, then turned on the furnace. Nothing happened, it just blowed out cold air for 6 minutes.
Then, we installed back the primary switch to its place; turned on the furnace and then taped on the fiber board many times [hopefully, it would close] but nothing happened. We then bypassed two secondary limit switches by connected the wires, but nothing happened either. We also took out the plastic hose between Combustion Air Inducer & Combustion Air Pressure Switch to cleaned it up.
Currently, we put back the first and the secondary witches and the hose to their places. Turned the Gas Valve off and then on. Again, our furnace just had only cold air for a couple minutes, then it was off automatically. We also notice that the Air Inducer did not run at all.
Brothers, would you please help us out. Your input and your suggestions are always appreciated and remembered. Gods Bless you and your family, Brothers.
