Fan comes on but the circulating pump does not come on. Hook pump up to switch it works ok. The ignitor will not work, no power to it. Get a F09 code error. This is a Munchkin boiler, model 80M-R1. This unit has work good for 2 years. The code error comes on at the very beginning when fan comes on. Check all safety divices all working ok. Thank for the help!

F09 means no flame detected, several potential reasons listed in manual.

it sounds like printed circuit board failure, if you can find the user and installation manual they will have a list of fault codes and what they mean
