Furnace blower cycling
It is summertime so there is no demand for heat. The temperature is cool s0 there is no demand for cooling. The blower on my furnace is cycling on and off. I turned off the thermostat and this had no effect. Still cycles. I disconnected the green wire from the thermostat to the furnace to eliminate a thermostat problem. The blower still cycles on and off. If I turn the main power off to the furnace and leave it off a few hours and then turn it back on the blower may not cycle again for 1/2 a day or a day but will eventually cycle. There does not seem to be any pattern to the cycling. Any ideas on what to may be the problem and what to check?
