Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now.

Is the burner coming on and running?

Customer: replied 9 months ago.
Problem is that the new circuit board has four San plugs. One for Pool one for heat one for fan one for him one and one for him t problem is that the new circuit board has five Fan plugs. One for Cool one for heat one for fan one for M one and one for M2
Customer: replied 9 months ago.
My old circuitboard did not have a fan plugged it just had the other four. When I turn on fan on the thermostat I get 120 V signal on the fan plug. However when I turn on heat the fan doesn't turn on the heater ignites but then turns off after a minute I believe the thermal sensor is shutting it off. I can't figure out why my fan is not turning on when I activate heat.
