    Pentair Mastertemp 250 24 VAC short keeps blowing fuse

    @ajw22 I’ve checked again that all connections are correct and that the voltages are correct. Also, I’ve received the updated board and 6 button membrane with FC connector. I will be installing them today and post the results. Thank you!

    Pentair Mastertemp 250 24 VAC short keeps blowing fuse

    @ajw22 this morning I reinstalled the original board and new fuse. I followed the step by step process of plugging in each J connector and checking the fuse. I was able to plug in all the connectors and the fuse is still good. I check voltages to the FS and they’re 24VAC but the display on the...

    Pentair Mastertemp 250 24 VAC short keeps blowing fuse

    @ajw22 the troubleshooting guide from the manual is what I followed. So you mentioned a 24v safety sensor which I had no idea about. How does that work? I ordered more fuses because I depleted the 10 I had so I’m planning on testing the original board again. I will return the board I ordered...

    Pentair Mastertemp 250 24 VAC short keeps blowing fuse

    @ajw22 the fuse doesn’t blow with just J7 connected to my original board but there's nothing on the display and the heater doesn’t start. When I plug in the new board just to J7 the fuse blows.

    Pentair Mastertemp 250 24 VAC short keeps blowing fuse

    @awj22 I checked the fireman switch and it’s in perfect condition. I also checked the wires to the FS and they do not have conductivity to ground so I guess the issue is with the control board? I actually ordered 2 control boards from amazon. They are the same model as the original one but look...
