I have a Heat Master MF5000e wood boiler and had an issue with it recently. The controller was hitting its low set point, which should engage the fan and open the baffle. But neither was happening. I called the dealer and he agreed to come up and take a look at it, a 3 hour drive for him. But the morning he was supposed to come up I tried turning on the boiler and behold!! The baffle made a clicking noise, and then opened and closed 4 times. Then it opened and the fan kicked in. It wasn't working for a week and now it is working perfectly. I thought the fact the solenoid was not engaging was not allowing the fan to turn on. But the dealer says they work independently of each other and the fan should come on even if the solenoid does not engage. Any thoughts on the issue would be appreciated.
