Assuming you don't hear any banging noises, that cycle is by design. There is a fault. 2 possible causes are the ignition board is bad, or the ignition sensor is not returning a voltage indicating the flame is lit. Take this out and put the ignition piece on your stove flame. Check for voltage while on flame (DC millivolt setting on multimeter). Put one probe on ground other on sensor lead. If it doesnt have voltage this is bad. If you do, its possible your board is bad.

The hot tub Hester will not light up pilot but does turn on and bow cold air


Glenn,
Many things could be wrong. First off, the exhaust fan turns always goes on when you turn on(up) the thermostat. It does that to suck out any residual gas in the combustion chamber. After about 10 seconds you should hear a click which is the gas valve opening to let the gas into the chamber. You should also hear a series of clicks for about 10 sec, which is the electronic ignition firing. If you hear the clicking of the ignition, but do not smell gas from the exhaust, then the gas feed is being blocked. If you don\'t hear the ignition clicking then the computer board is detecting a fault condition by one of its sensors: over-temp, water flow, exhaust fan . These are all in series and if one doesn\'t pass then the ignition won\'t fire.

Jandy lite 2 pool heater will not stay lit.


I'm having the same issue as the above user with Jandy Lite 2 (which from what I can tell stands for the number of times that you can get this POS to work annually)!
The unit LIGHTS OFF, but WON'T STAY LIT! Igniter engages, gas valve opens, unit lights, burns for 10 seconds, and flames out. Error code FL 2, after third attempt, already replaced the flame sensor....

Your thermocouple has gone bad.That is the brobe the pilot light hits.It is simple to replace.Turn gas off to the unit. Unscrew thermocouple from gas valve.The probe mite be just snaped in or it mite be held in by some screws. Dont bend any thing at the brobe end.Remount everything and check for any gas leaks.

Service light on


I just had the same problem resolved, my mastertemp 400 would run up the temp to 82F and then cutoff, the service light flashes and then 50 seconds later the heater would restart and run for 2 minnutesbefore shutting down again and relighting in 50 seconds. Repeating until the temp setting is reached.

I had the pool guy out 3 times until he found a bad thermal regulator valve (kit #77707-0010). Once replaced the heater runs great.

He told me that it's my pool chemestry that is to blame, I had it checked (like I do weekely by me and monthly by the pool supply store) and it perfect??? I'm now questioning what caused the corroson and stop it from coming back?

I hope tis helps.
