Hello, I purchased a new replacement control board (Raypak 013464F PC Board Control Replacement for Digital Gas Heater--601944) from Amazon for my atmospheric heater M266A. I had already purchased a used one off of ebay, but apparently it came off of a Lonox unit (even tho tab was still intact?) and so it fired off a Lonox error on boot and didnt work. Raypak support told me the control board has the same part number for both Atmospheric and Lonox units (PC Board: 013464F)

With the new board installed, it blew the onboard 5A fuse after a hour or two of operation. I replaced the fuse and then it immediately blew again when powered up. Before this I had also replaced the A/C power convertor on my heater with a new one, and also the pilot light assembly with new. So now I am out of ideas on how to proceed....any clues or ideas for me?

THanks in advance!!

Look for a pinched or burned wire, especially if it is against the panel at the back of the cabinet. Did you wire the transformer for the proper voltage?

THANKS poolman. I I don't see a pinched wire but I will double check everything tomorrwo. the wires from the ac/dc adaptor to the control board are new and shipped soldered onto the converter when i bought it, but the utility wiring from my home to the heater are still the same. It appears to be a 220v, because when i examine the breaker I see two 110V circuits tied together(?) to run the heater circuit. anyway, i kind of doubt I could have gotten that wrong and still had it work for over an hour if it indeed was meant to be wired for 110 and not 220. But I am completely ignorant about home electric. So I will try and double check with a multimeter or something.

I appreciate your reply Poolman!
