We have had our newly installed pool/hot tub for exactly 1 year and 2 months. Meaning.....warranty was up 2 months ago. Now my heater will not kick on. We have replaced the ignitor and that did not fix the problem. No code on the heater and the pool handheld remote thinks and acts like it is on, the heater just does not fire up or get hot. Not sure what to try next. Does anyone have any suggestions on what I should test or look for next? The heater is a Jandy JXI 400kBTU. If I need to replace the heater, should I replace with a different brand if it is only going to give me 1 year of use?
