Furnace has been running since fall, and all of a sudden i noticed on Saturday that the heat signal on the programmable thermostat was flash heat on...and i walked over to the vent and just blowing cold air...Any tips or ideas would be greatly appreciated here in Canada

Hi,

Don't have any data on it, is it an electric furnace ?


Thanks,
Robert

no it is a gas furnace a/c unit combined..outside. In my searching for this brand I found it was bought out by International Comfort products

Hi,

Have that info, but no data on components, specs , etc. which is needed to try and help from here.


Is it a standing pilot light, electronic ignition, etc. ?


Does it have a small booster combustion motor ?



Do you have 24vac at gas valve ?



Thanks,
Robert
