Lennox Heater Light flashing
My thermostat is clicking when I turn the temp up, but the heat is not coming on. I pulled the panel off and there are two green lights. The light on the left is flasing, but when the thermostat kicks on, both lights stay on. Any ideas before I have to call a HVAC company out on a Saturday?
