Had this fault on my 2015 pool heater. Manual said check connections. Bought a new fusible link on amazon. Touched the connections to the existing fusible link and the connector fell apart. Same with second connector. The high heat over 9 years of use deteriorated the cheap OEM connectors used. Put new connectors on the two wires ($5 total from Autozone) and installed new fusible link. Works great now. Easy fix at a low cost. Sorry I did not take pics as I repaired it. Next time.
