Breaker is probably weak or wires are loose on the connection. If you want to try tightening connections first open breaker panel and turn off 40 amp breaker. Take flat heat screw driver and tighten the screws. If that does not work breaker is bad replace it. Breaker is about 10.00. Pick up at Lowes or Home Depot. Russ

Heater can go bad but they usually just open and amperage drops. Russ
