In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have been getting an occasional error code (F09) on my Munchkin Contender gas fire boiler. When the error comes in, I have to reset the unit. Sometimes this takes 2 or 3 resets before it starts working again. I have spent too much money calling out technicians to repair this unit, so I want to fix this my self. Can someone help me solve this error? I believe it is related to the flame sensor.
