Question about Goodman GMS90703BXA Heater
Blowing cold air >has pilot light on<
Here is a manual that has the parts break down. Click Here=> Goodman GMS90703BXA Sounds to me that your gas valve is not responding to the thermostat calling for heat. Double check gas valve settings and also have someone near switch the heat on to say about 90 degrees. You should hear a relay click sound to pull the gas valve open. Also Click Here=> Appliance 991 Help Forum That manual that is on that page has all needed information a tech or installer will need so please read carefully and use caution. I find that very odd that the fan will run before the heat exchanger reaches higher temperatures. Indicating a possable electronic failure. It must wait until hot enough before fan comes on. In left sidebar and 7 links down is the diagnostics PDF. Click and save if you like. Contact me here or from that site and I will try my best to assist you while we try to find out why the electronics is allowing fan to run first. There are different models on that PDF so keep that in mind that all models listed are somewhat the same yet not exactly. There shoud be a light code to look for that just may point to the problem the furnace is having. If not comfortable then please have a qualified Technician help you solve this. Just let me know when ready, Thanks, Sea Breeze
