furnace air pressure switch replaces goodman part # b1370142: amazon.com: tools & home improvement

If you're like me, you got the 3 blinking lights and no heat.
For some reason the first part did not work at except the replacement did the trick..
Also, before the part arrived, I crossed the wires over AFTER letting it begin the start up cycle, to provide temp heat.

It's 66 in the house, thermostat is set for 74.
Remove the cross wire, let it begin to cycle up, put the cross wire back on, let it fire up, and if will stop at 74.. Toggle full review text aria-expanded= false role= button data-action= a-expander-toggle class= a-declarative data-a-expander-toggle= { allowLinkDefault true, expand prompt..
