I have a Heil 93% and I couldn't get any thing to kick on. I found by looking on the mother board 3 heart beats which tells me by the guide that it is pressure switch open when should be closed so first I disconnected lo transition switch and jumper-ed it. And hi blower switch and jumper-ed it and the squirel cage (blower motor) kicks on the inducer motor does not kick on( however connecting to line voltage it works) it gives me 2 beats which tells me pressure switch closed when should be open. I have disconnected thermostat connected are,w,g together.any help would be appreciated
