Started with a customer 3 years ago, replaced an igniter...two weeks later, it burnt up, replaced it again and returned the old one for credit. Beginning of the next season, igniter blown again. Replaced it adn looked into the issue and could not find anything. 3 months later, igniter blown. Found that the the control board was not turnoing the igniter off completely and there was 42 volts leaking through the element all the time. Replaced the control board and igniter...problem solved right? Wrong, dude called me today saying the igniter is blown again. HELP! FYI voltage from outlet appears to be okay with surge protection.
