Hi everyone, i have a older minimax plus that was working great. I went to try and turn it on yesterday and the service light is on along with just the power light. pilot is not doing anything. but when i turn the temperature down the service light goes away but still no pressure or heat light comes on or any spark from pilot. i tried jumping the pressure switch/wires and still nothing. I would greatly appreciate any suggestion on what i can try and check thank you.
