    Pentair Minimax NT won't fire

    My Minimax heater will not start. When I turn it on and adjust the thermostat, I get a "click" at the control panel, and then nothing. The pressure and thermostat lights are on. I checked the blower, and there are no obstructions, and it spins freely. There is no gas smell either. This happens in both pool and spa mode. There are no errors, and the diagnostic LED doesn't blink.

    I did use search, and found one thread that seems close to this. They jumpered the blower, but I'm confused what was jumpered.

    Usually, when this happens, it is due to the vacuum switch not "making", aka closing. That is usually the either tube coming undone, has a hole letting air in, or the fan isn't spinning fast enough. The vacuum switch has been proven reliable. Without it making, the gas won't open.

    Check my post from 2 years ago. Perhaps it is similar issue.
