I have a image spa hottub, think it's from around 2003 or so.
All the pumps and light works but I can't get the heater to work (properly).
First I replaced the heater with no difference. Just replaced the board and still no heat.
The heater light doesn't come on but I've noticed if I turn the set temp down to below the current temp I can hear a relay cilck.
I've put my voltmeter onto the heater terminals but it looks like there's no voltage.
Any ideas?
The old board is ICON31R2A and I ordered a replacement which said it was that model, but what I received was:
2000LER1E
OF19
Everything else on the board looked identical.
