I have a Rheem furnace model# rrka-a024jk08e. In the past week I have had to replace the main control board because it was burnt up. After replacing, there is no power going to the direct spark igniter. The blower fan and inducer fan run though, even with the thermostat in the off position.I bypassed the limit switch and the gas pressure switch. Still did not work. Any help would be appreciated..
