we recently bought a house with an in ground pool and a Sta-Rite sr2000na heater. This spring it did not work - error code E01. a friend and i opened it out, cleaned out the mouse house and found & spliced back together a broken wire to the thermistor and presto - the heater worked. We noticed a lot of nearly chewed through wires so my husband and I ordered a new wire harness and spent the afternoon replacing it and the transformer that came with as pentair had changed the wiring from a 5 wire plug to a set of 3 wire and a 2 wire plug.
Sadly, the control board does not even light up and of course the heater does not work. (we did reset the breaker)
any tips/advice on how to start trouble shooting ? I know this is a long shot but a new heater is $$$ as may be the bill to pay someone to troubleshoot it ...
