Jacuzzi JHX127 heater panel frozen

[tonygret]

I am not sure what happened, but over the last week of so my pool heat temp got set to 104 and I can’t change it. I am the only one who has ever used the control panel and I never set it past 85. I thought the panel might be locked, but the LOc doesn’t show when trying to change the temp. In fact the panel doesn’t respond to any input except it switches from current temp to set temp (104) when pressing the temp buttons. I switched off the breaker for a few hours but that didn’t help.

My back yard is blocked almost all the way around by a wall and fencing. It’s off the beaten path and the only people who go back there are the gardeners. Maybe someone messed with it, but I highly doubt it.

The odd thing is it does show the current temp and the low flow occasionally when the pump is set to low. But it works ok, in that the fan comes on followed by the compressor and it tries to reach 104. How water is coming out into the pool.

Any help would be appreciated. Thank you.

Sounds like a bad keypad. You can try and open up the unit and squirt some contact cleaner on the buttons and control board.

As it turns out, the keypad/control board needed to be replaced. Jacuzzi sent me one at no charge based on the 6 year parts warranty. It was only attached with two Philips screws, but the other end of the wire connected to the main board. That required taking out about 20 other screws.

In the end I have a new and completely updated keypad for the $14.00 cost of shipping. No screws left over.

Thanks!
