Question about Heating & Cooling
Look for limit switches, you can find one or two manual push button switches near the exchangers. If that doesn't work, find the primary limit switch it is on the wall of the exchangers and does not have a manual botton to reset, get a paper clip and bypass those two wires, turn power back on then see if it works... Try the same thing with the manual limits, they have one wire coming in one going out, if continuity is broken furnace will not start. You must not leave the paper clip in, take the bad limit and replace it..
