I am having a problem with my HVAC system as described below:
The thermostat (White Rogers) has two settings for the fan (auto and on). Right now, the fan it is set to auto. It has another switch with three settings (i.e. cool, off, heat) and it is set to off.
The fan still comes on for a few minutes every now and then. Since, the system is set to “off” and the fan is set to “auto”, the fan should not come on at all.
The furnace works perfectly and when I turn on the heat it turns on the fan too. So there is nothing wrong with the system other than this fan running every so often.
Here is what I have tried so far:
Changed the batteries in the thermostat.
Changed the air filter.
Reset the thermostat to factory setting so that it is not programmed.
Please help me fix this problem.
