Question about Heating & Cooling
Hello - my Rheem Criterion II (old model) would not ignite the flame.It worked until a couple of days ago. When I open the cover and startthe furnace, the green LED is blinking twice then pause. According tolabel, the pressure switch is open. How can I fix this? Do I need toinstall a new pressure switch? Please advise.
What you need to do is take and inspect the hose that goes to the pressure switch and make sure that it is not dry rotted. if it is and the combustion blower is running then firsat try to cut the hose down and slip on a better piece of rubber. If not then replace the hose,
