422 question
Question-- I have been having problems with a 422,if it goes to high or if it runs alot. The issue is the fuel pump makes noise and the flame dies. I assume that the pump is starving for fuel.I always keep the basket clean,today I took out the filter in the clv. When all cleaned up and restarted, ran fine,even on high(little too much yellow), then I went in the other room,came back and the burner lights were flashing. I waited a few minutes then turned it back on, when it got cool enough it restarted, after a 8-9 mins. the pump lightly started the noise, I hit the valve reset a couple of times and it has been fine. It is winter here in Maine and I am just using this heater to get by until they install new furnace. I may decide to keep it to use in addition or master bed room,would probably rebuild it then,but now I really need to keep it running. Do I need to take out all the fuel components and clean every thing?
