Question about Pentair Minimax Ch 400,000 Btu Propane Pool Heater Millivolt Ignition

Heater not working

My old pool guy bypassed the switch to indicate if the pool temp was getting too high. For the 2nd year in a row my manifolds burnt. My new pool guy replaced them but when he went to undo the bypass and hook it up the right way he said it isnt working anymore. Any ideas?

Yor heater has 3 high limits and a flame rollout switch(aka thermal fuse). be advised that bypassing safetys is not recommended and is dangerous.these component failures are symptoms. we need to find causes.if limits are failing look at sooted or possibly a nest on your heat exchanger. if its a flame rollout problem look at obstructed burner or oriface.

I have a Starite heater, natural gas. I replaced the thermistor for the second time in two years. The problem again has returned with the R6 code. The heater just doesn't seem to get hot enough. Shoul


you might want to add a bypass to the heater and not let the full return water through it this is called temp rise to slow the water down so it gets hotter

Hello - I have a Pentair MiniMax NT that is aprox. 5 years old. We have never had any problems with it till this past week. We went to turn on the heat for the jacuzzi, and nothing. The unit shows the...


HI is a code for Water temp over 114. If this is what you have the temp sensor has gone bad. Or thermister. It will be a small tube that slides into the water manifold with two wires coming from it. A white nut sets it in place unscrew this pull out follow the wires to unplug then slip the new one in.

It is also possible that you have enough water flow to close the pressure switch circuit, but not enough to keep the water from getting to 114 F by the time it reaches the temp sensor.

Also, the bypass valve might just need an adjustment . If its bypassing too much water, you will get this code as well.

Hope these ideas help

My pool heater exchange is leaking. Is it worthwhile replacing this part $ 699.00 plus labor ? The unit is 4 years old. Can the old part be welded or sodered?


Along with the exchanger you will need header gaskets, manifold gaskets, Pressure switch and tube, igniter or pilot and maybe a temp sensor. I count on all of these when I do an exchanger, total cost about $300.00 Now your over a grand. Labor about two to three hundred, if nothing goes wrong, and hopefully it all get's done right. Now your up over half of a new one and 90 days on parts. I know I make money at this but I make money at rebuilding heaters also. I usually try to get people to go towards the new heater.
Then take a course in pool and spa chemistry. 99.9% of the time this is the cause of a bad exchanger and that is what hurts the other components at the same time.

Ref: Sta-Rite Max-E 400. Pool temp is about 75


Your temp sensor has gone bad and will need to be replaced. It's a small tube that slides into the water manifold and you can follow the wires back to the board. Just unplug and set a new one in place.

Fixing our hotel's Hayward CSPAXI55 spa heater.


You can probally get a manuel on line if you go through Hayward.
When he took the old one out he probally just wired the circut together where the temp assembly goes into the cabnet in the top right front of cabnet in the upper panel. Then the temp probe runs around the side to the water header or manifold. If this is in the orignal spot it is on the right of the heater and easy to find. I'm not sure but if the exchanger has been turned then it will be around the back side of the header and it will be on the left side of the heater. Geting a manuel for this is a good idea anyway, good luck.
