I wonder why your question ended up in the wrong category.

Now that we know that it is a propane heater and not a TV I still don't know the brand name or model. I think you said 5th. wheel.

FIRST ... CHECK YOUR FILTER !! IT MUST BE CLEAN ! THERE IS A PRESSURE SWITCH ON THE HEATER WATER INPUT LINE . IT MAY NEED TO BE REPLACED .. JAY.. THE POOL PUMP REPAIR GUY IN LONGWOOD FLORIDA

3 main possibilities.
1- ignitor
2- bad ignition control module
3- bad flame sensor (flame rectifier)

its probably the flame sensor.

Is it Propane or Natural gas? Check your gas supply pressure.Also, open up control panel, accessable by removing the plastic exterior panel with 4 screws, check to make sure no critters got in and chewed wiring.

the problem is in your motherboard..this most cause unregulated flow of power from the source electric..but if the green led is off so its the processor.try to test it with a motherboard tester..or get another board that same spec with the you have,and transfer the processsor if it is working

The users manual for these pool heaters is very thorough and address this problem in the flow chart. Try that and see if you get the solution you are looking for. A lot of the questions needed to troubleshoot cant be answered unless you are looking directly at the heater.
