My boyfriend recently unplugged our Goodman GMT070-4B to use the outlet, it has not worked since he plugged it back in. We followed the instructions several times to make it ignite and nothing is happening. The motor starts but nothing ignites and nothing clicks. Any insight is appreciated. We are freezing!!

first thing,,,,the wiring on your furnace shouldn`t be wired in such a manner that it can be unplugged (assuming it just plugged into a wall socket),,it should be hard-wired straight to the breaker/or fuse box and wired to its own breaker
