If the board is sending 220 to the heater, I don't think it's the board. @ 40 bucks for a heater I'd be trying the heater first. Tman?
Is it wired for 110 or 220? Cause now we have a different scenerio than Doc just said. If it's wired for 110V then you have to check across the heater terminals for 110 volts. If it has 110v when it is calling for heat the element is bad. If it doesn't have it then the board is bad. 220 same except 220 across the heater terms. Resistance will verify it but no one ever does that cause it will only show the progression of failure in the element and those specs are hard to obtain for that particular heating element.
