I just bought the house with pool/spa and it has a Jandy LITE2 heater. The first day, it heated up the spa great. Since then, it will only heat up to about 94 degrees. Some photos here: https://goo.gl/photos/hKm9CKKw9spLkotNA.
Any ideas on whether this is something that can be fixed, or should I look to replace it all together? If replace, any recommendations on a heater that would fit into same area and with same pipes?
