Goodman runs 10 minutes and shuts off
I had a goodman furnace put in about 3 years ago.The furnace lights for 10 minutes then flames go out but inducer motor still runs on and off then 5 minutes later it works again for 10 minutes. I am in a wheelchair so I can't work on it myself so I hired a company. They charged $85 to walk in the door. They changed the pressure switch for $75 labor the parts were under warranty. After they left I find it's doing the same thing. They come out the next day and replace inducer motor for $110 labor. I get up this morning and it's 62 degrees in the house but the thermostat is set to 68. I turn the furnace off and on and again runs for 10 minutes and shuts off just like to start with. Now they want more money to come out again. I did not replace the thermostat but it is digital. Am I getting screwed by this company? And what else could it be?
