My heater is a Temptstar installed in 1993. The problem is when I start the heater is burning the gas but the blower doesn't run, after couple minutes stop burning gas and the blower Runs for two or three minutes, when blower turns off the heater burns gas again and keeping doing the same all the time, sometimes runs like good burning gas and blower working at same time but for one minute and then the blower stops again and heater works for a minute, stops, blower runs. Etc.
Anyway, A good friend who lives in Canada and worked with HVAC years ago told me by phone that can be the relay so I replaced twice for a good used ones(the new one is very expensive and more now that I don't have job in two months)
But nothing.
Last summer I had problems with the A/C and two "technicians" checked and moved cables but after all both said that I need to replace all unit($6000)
My friend in Canada said that could be wires or cables in wrong place but how can I get a diagram?
Please help me...
