The Goodman 1370910 main limit switch is a 1/2” disc designed to shut off the burner gas should the outlet (bonnet) temperature exceed the maximum design outlet air temperature. This switch is not adjustable. To check the operation, block the return air flow through the unit temporarily. The limit switch should function and shut the burner gas off within a few minutes. Remove the blockage and allow the switch to cool sufficiently before reestablishing burner flames.
