Please Help me Seattle Pioneer

SeattlePioneer... I have what appears to be the exact same problem that rabois described. I checked all the hoses and made sure they were clear. Suspecting the pressure switch (after some trial and error) I ended by removing the hose from between the pressure switch and the burner box and was able to get the furnace to ignite. Since it is very cold outside here I am going to let it run long enough to heat my house back up but obviously am not comfortable defeating the safety mechanism for long. Any thoughts on how to DYI repair the switch? Or where i can find the part? My part searches have turned up nothing thus far that is a confirmed match.

 

Please don't revive an old thread. it can be confusing and even dangerous.


Start a new thread and report you problem.

 

I have made this its own thread.

 

1) The furnace shouldn't work if the pressure switch is disconnected.


2) By operating the furnace with the pressure switch disconnected, you could easily have a hazardous condition in the furnace.

3) Guessing that the pressure switch is a problem is not a good diagnostic method.


My suggestion is to recvonnect the pressure switch and to carefully observe and report here the sequence of events that occurs when the thermostat is turned up.
