I went to replace a T Cell. When I tried to enter the correct setting for the new cell, I found noticed the LED display light on the control panel wasn’t lighting up. It’s basically is unreadable. Everything else seems to be fine. Any suggestions?
Hello Ginny44669 - A very common issue is a blown fuse on the circuit board. It’s a small 20 amp yellow fuse. We have a guide and video titled “How to Replace a Hayward Aqua Rite Fuse”.
Check out the Aqua Rite Troubleshooting Diagnostics Manual for a more detailed list of potential causes.
