Works perfectly. The temp increase button and the spa on button were not working. Also, the heater would turn on by itself and waste propane. After looking up a video on how to replace, replacement was super easy. Now, realizing that it is not an OME replacement, I just want to see how long it will last.

I have a JHX140 Jacuzzi heater. The membrane pad went bad. Somehow the ribbon cable on it got fried. Not sure how that happened. Anyway, the original pad only has 4 buttons: Mode (Heater/off), Up, Down, "Jacuzzi/SPA". They don't sell a replacement. Just an upgrade pad/control board that cost north of $500, if you do it yourself. So I took a shot at this membrane pad for under $20. A heil Mary!. It has 5 instead of 4 buttons. I used Bread board jumper wires to map my 4 pins to 4 of it's 5 buttons. I then stuck the new pad on top of the old pad. Worked like a charm! With a little black tape to hide unused parts, it even looks good. FOR LESS THAN $20 BUCKS!. That maintenance trap didn't get this guy :).

I have a water heater for my pool and I thought that the entire system is damaged hi research, the bit and found out that the display might cause he issue. The main problem was that the heater was constantly turning on even you shut it off. Finally, I replaced this part. It was a 5-minute fix and it worked well

My Pentair Mastertemp 400 was turning on randomly. The hearted was not turning on when the Spa button was pushed, but would turn on when the pool button was pushed. Research told me the likely (and least expensive) issue was the membrane switch.After replacing the switch, the heater works properly again. The fit is perfect and instillation was easy. I subtracted one star because the switch was supposed to have no logo according to the image. This is a small issue when compared to the $100+ savings over the OEM switch.
