When on gas and the box reaches the preset temperature the burner shuts off. What causes the burner to relight when the thermostat calls for cooling as the box temperature
rises?

Hi, thanks for your patience,,,,,,,,,,,,,,,when the box calls for more cooling, the thermister located on the fins (right side) sends a signal to the control board, where in turn it goes into the ignition sequence, and lights the burner, please get back to me for clarification if necessary, thanks michael

There is no control board on the N 500. It does the things you said except that when the t-stat/thermistor calls for cooling the burner doesn't light. The relighter tries and tries but the gas valve doesn't open and the burner doesn't light. The burner lights
and burns on the initial startup. It will not light when the t-stat/thermistor calls for cooling thereafter.You tried and I think you should be paid.
