Just wondering if you one have this problem with the Frigidaire model mentioned above. I bought the house during the summer of 04. The system has been working fine till the now. Sometime there is only cold air flow out of the duct instead of warm air. I open the panel read the schematic and noticed the yellow light is flashing continuously indicating; occording to the wiring diagram pointed out the "Low Flame Sensor Signal". the system sometime would not start up in middle of night.
I also have noticed there are four rollover switch. How do i reset them? Any suggestion, recommendation, Plz help thank you so much.
(frigidaire furnaces 80-90 upflow furnaces)
