Question about Pentair MINIMAX NT TSI IGNITER

2 Answers

Heater starts and then stops.

I have a pentair heater which when started the fan turns on for about 30-45 seconds and the just shuts off, we were told it was a faulty mother board. I replaced that (for a penny or two) but it still does the same thing. Any suggestions?

    I have the same issue. The heater fan starts, the burners light for a few seconds, then it shuts down. The service light comes on on the panel. I replaced the board, but it still has the same problem.

    Your lucky, I dont even get the burners to fire up. I was quoted $145/hr to look at it plus parts. all the companies I have talked to say they replace item after item till they located the deficient part. why do I know I will end up with a $1200 bill.

I will keep you posted. I have aquired all the service manuals and I am in the process of taking the heater apart. It is not the motherboard.

We had the same issue. Fan worked, gas flowed, burner glowed, but would not ignite. Heater would shut down after a few attempts and give the E04 message. Service Tech replaced the ignitor, now it works.

My wife said the pump timed off and the heater was heating. She shut the heater off and restarted the pump and now the heater won't ignite. The red light blinks three times and I am not sure how to get it...


The fan will continue to run for a few minutes after the pump turns off to purge exhaust gasses.If it was still heating you have a problem. To reset the heater,turn off the pump breaker for 30 seconds. After that you need a repairman.

I have a 250K mimimx nt heater that has been inactive since last spring. I just tried turning it on and fan starts and then heater clicks on for a few seconds and then shuts off. This happens a few more...


This is a fan code. If your fan is running then the air pressure switch has a problem. On some units the gas pressure switch is on the same circut. This would be the NT LN model. On this one gheck to be sure your gas is on and bled out first. If this is a LP heater be sure you have enough gas to run it. Most heaters need at least 30% on the tank to get enough pressure to run the heater. If it is the air pressure than you need to check your air flow. Be sure to check you don't have bird or rat nests in your exaust or on the burner tray assembly. If you don't have any of these problems you may need a new air sensor. I hope I have helped.

Minimax NT 400 TSI Heater problem


I bet that your 15 seconds of flame are more like 7 seconds. The time is very important. If the flame is not recognized after a specific time the valve is shut off. If the flame sensor is GOING bad but still make some rectification then you may get the issue you are having. I would start with the flame sensor and work from there.

Flame wont stay lit


Sounds like a flame sensor problem. The board is not getting the proper signal from the flame sensor so it thinks the burner did not light and shuts the gas supply off. It keeps the blower operating to ensure that no gas is accumulated in the burner area. I suggest you contact a local mechanical contractor to service your heater.

Pentair Minimax NT 400 heater. fan keeps coming


Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

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.
