Primary Controls Dying

Nikkat01Nikkat01 Posts: 1Member
I woke up to a completly dead primary control. I installed a replacement. Everything fired up fine and ran for about a minute. Then it shut down and no power in the new primary control unit. Anyone know what could be causing this?

    What primary was there and which did you replace it with? Where are you measuring no power?

    If the new primary itself actually failed (check the power feed as @woodrow and @CTOilHeat have suggested first), check for a bad or non existent ground or swapped neutral and hot feeding the unit. Also check for "dirty" power (spikes, dropouts).
