As JerryFin mentioned, there are cracks in the solder on the circuit board edge connector that cause the unit to stop heating randomly. All you need to do is pull the board and re-flow the solder.
If the heater is operational, working and the top of the heater is hot, and you do hear the combustion of the gas, see flames in the burner tray area...
.... then your heater is heating the water!
If there are flames in the heater, the heater is normally doing its job. Most people are not aware of the time it takes to see a "Temperature Rise". The average temperature rise is dependent on your heater size, the ambient temperature of the time of day you would like to use your heater, the wind/breeze factor as it goes over your pool surface. Is the pool waters surface covered? etc. All of this is a factor on how quick the temperature will rise. It is possible that you will not feel warm water coming from a return fitting.
Another common mistake some pool owners make is the system is on a timer. And the desire to start the initial warming of the water starts with the flick of the heater switch and then a few hours later the pump turns off and along with it, the heater. The heater will only work, if the pump is on and circulating the water! No circulation, no heat! So if you have a timer, remove the "Off" timer pins and allow the heater to work.
flame should be blue, this sounds like a natural gas unit (orfice) running on LP. Lp is burns hotter than nat. and will burn orange. and use huge amounts of fuel.
Could anyone tell me where on the control panel I would find the Diode D1 on the board?
"agreed; it's usually the diode D1 on the board...a 75 cent part"
If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts
right back off, then you need to clean your flame sensor with light sand paper
or steel wool. You might need a new flame sensor, but most of the time they can
be cleaned an will work well after cleaning.
It sounds like your pool heater is not firing. I would check several things: the burner might be blocked and clogged, the gas valve might need to be replaced, the direct spark module might be malfunctioning, or the combustion blower might be cleaned. One of these is probably the issue. A service man can repair all of these problems.
Hi,
I'm not trying to be a smart alec but, did you know that that yellow light might be part of the diagnostics. If you can read the tiny print on the back siide of the acess panel. There should be an explanation of what the light means. At least thats how mine works.
hope that helps,
