Chlorine in-ground 35,000 pool. The heater is 5 to 7 years old and this is the first season I've had problems with it.
The unit is in "Remote Off" and I do not have a remote.
Here's what I get:
1. Switch on unit is "Off".
2. Turn switch "On".
3. Get "RV 1" for a few seconds
4. Then get "CFH" for a few seconds
5. Then get "CLK" for the remainder of the time
Same result if Mode is Spa or Pool.
If I use Mode from Spa to Off to Pool all I get is "CLK"
Never see "SPK"
All of the wires seem to be in good shape but I have not looked at any other than what you can see when you pull off the front cover.
The unit has come on and heated up a few times but it will not recycle to heat again.
Thanks for any assistance.
