Just seeking a third party opinion here as I am having a new Pool tech out to look at my unit. Currently have a Raypak 406A propane heater which I installed myself with no diffuclty last year. Worked well from July to end of season. Only major worry was when the unit was delivered (on a rainy day with my wife at home) we signed, only to open box and there was a 2" crush on the corner of the unit. Raypak sent me a new top piece, the rest of the unit seemed ok but I was worried about internal cracking or a structural issue that may not show up for a bit.
Anyway, first time using the unit this year after opening from winter, I run the heater and get "High Limit 2" fault.
Various other posts in the interwebz says:
1. Possible low flow rate
2. Defective high limit switch
3. Possible stuck bypass valve.
I would rather not take the unit apart and look for the issue simply because I would not know what to look for. Thus I contacted a Raypak recommended tech to look. Is this something a) common; b) I can easily fix; c) possibly related to the damage in transit last year?
I am still going to pay the tech and hopefully have warranted parts if needed since the unit is under 1 year in age. Also by posting this the problem and answer are there for future lurkers.
