I'm assuming, first, that your pump is running when you turn up the temp, otherwise, the high temp switch will turn off the gas. Then, it could be any of the switches hooked in series that must have flow thru them to let yhe ignition open the gas valve. ie could be water-flow switch not sensing enough eater running by it. Bypass (jumper) one at a time to find the culprit. Good luck...

Fusible link or the Roll out switch are one and the same...if it burns out, or provides 'Open Circuit', then you had heat or flame exit the front of the heater instead of up!This is a problem that needs correction.Most common reason, Sooted Heat Exchanger / Tube Bundle.dissassemble and clean it - not with a brush!!!2nd possibility, especially if outdoor installation is a 'Downdraft'.Don't just replace rollout switch - FIX the reason it burned out!

there should be 3 heat sensors on the unit. Incoming water to decide if it needs heat, outgoing water, and a sensor on the burner(flame). the in and out sensor should be behind a panel near the inlet and outlet pipes. The burner sensor is more tricky usually near the igniter or below the heat exchanger inside the unit.
