Yorx Furnace will not ignite.
I have a Yorx Furnace Model # P3HUC20N9201B with a White Rdgers 50A-50-241 controller blinking 3 times. The exhaust blower comes on but nothing else happens. What is wrong and how do I fix it?

Start by looking for a service label that translates the LED code - usually inside a service panel or on the control itself.

If you need a new circuit board the new number is
50A55-843
3 flashes, then pause Pressure switch stuck open
Jump pressure switch and see if it fires up. If so check the hose for leaks if none replace the pressure switch with same part number.
Your unit might go into lock out if that is the case turn off power and turn back on. If still a problem the unit will reset automatically after one hour.
