My Skypak furnace does not work. It works in A/C mode, but does not work in heat. Pilot cannot ignite. When I turned of HEAT on thermostat and fired pilot manually it stay on, but when I switched HEAT ON on thermostat than pilot OFF. Fan does not blow any air. Same problem I had 4 month ago. Plumber replaced gas valve and it start working, but I do not think this was a problem.
Can anyone help me, please.
Thanks Y.
