I have an Aquacal heat pump (SQ110) and it appears the temp sensor has gone bad. The temperature on the display is 10 degrees off from the actual water temperature. The heater runs fine otherwise. Can these be replaced easily?

I have an IC20 pentair Intellichlor. And I noticed one day that there were no lights on the cell at all. After troubleshooting, I found that the fuse in the power center had blown. I replaced the fuse and turned the system on and the fuse immediately blew again. I'm wondering if the cell is...
