I checked the power and I am getting 29v at the wires. It works briefly
when I remove and reattach the unit. I may buy another to see if it is
in fact the unit. $90 may save on a hvac repair fee
Mine does the same. When I remove the thermostat to check the wires, the
thermostat works again for a brief time. Could there be a fault with the
thermostat?
