It seems like since I put the new relay board in when I use the breaker to turn it on I hear a loud clickthan I ever have heard before
But the heat or the red light on the main board never comes on
Did you mean that the jumper control switch on the main board is probably bad??
I assume that means that you have to get a whole new board main board that is and hopefully the old relay board is OK
I unhook the ozonator from the electricity from plug-in
Still lots of bubbles lots of flow coming from the drain
does not appear to be any Obstruction and plenty of circulation pump flow
keep in mind that this is a new heater relay board installed on existing or original main board
I think the problem is that the main board is not allowing any electricity to go to the heater Since the red light for heater on never comes on the main board
Looking for some help out there. Just replaced the heater relay board and the heater did not replace the main board. It worked great for a while and then all of a sudden the red light on the main board would not light up the green light on the main board was lit green.
The controls change the temperature OK and the red light shows up for power and control but it does not heat up. This red light is on the control the red light on the main board does not come on
does it sound like I need to also upgrade the main board??
Thanks And any help would be greatly appreciated
The picture is upside down The green light is on the two red lights are off
this is on the main board
The green light is limit OK
The red heater on never comes on even though I just replaced the power relay board.
there is a green light on the power relay board the new power relay board appears to be working fine the only problem is the heater never gets power
Limit OK green always lit
htr on - red light never comes on
Bottom red light on the main board never comes on
Small green lit light Constantly on the power relay board
Keep in mind that this is an updated power relay board with a main board that is 20 years old
