Trane Gas Furnace Problem
I recently experienced a problem with my heat. I have a programmable thermostat and noticed that the heat wasn't on when it was suppose to be. The temperature was set to 75 but the temperature in the room was only 68. I canceled the program and manually set the temperature again to 75. The heat came on and everything seemed fine. Then about 10-15 minutes later cool air started to come through the vents. I went outside and found that the my Trane gas furnace had turn off even though it hadn't reach the set temperature. I played around a little with the thermostat but nothing fixed the problem. Then about an hour later warm air started to come out of the vents. But then about 10-15 minutes later the heat turned off and cool air came out of the vents. It seems like it can start up fine but then something is causing it to shut off like it was overheating or a safety switch is be activated. Any thoughts? Thanks.
