Gas Furnace turns off after 5 minutes.
I have this gas furnace every time I push the reset button it will turn on but after 5 minutes. It will turned off again and will never turn back on unless I push the re-set button again. I just re-placed our thermostat because I thought that might be the problem but after installing it and set it to 90, still the same push the reset button then after 5 min. or so it turns off again. Can someone please help me maybe anyone here have the same problem. I appreciate it. Thanks
