Start at the begining, make sure you have power going to the heater and check to see if it is 110 or 220v. If you have power and it is correct the next stop is your transformer and how it it wired. You should have a diagram inside the main power junction box for the heater. If you have good power in to the transformer and 24v coming out it will be in your safty circut. Roll out switch and pressure switch are good places to start. The main power or transformer are probally where you should look.

When I turn my mini max plus 400 heater on it clicks then nothing happens, what's up with that


If it is clicking it is trying to fire (calling for heat). This indicates that the internal safety loop Tstat, and IID are working. It is either a bad gas valve, your ignition wire, or lack of gas. If the gas line had been open for servicing for any length of time it can take a while for all the air to get out. Best call out a tech to do the repair, you are literally playing with fire.

I have an mini max nt w 6800 controls ignitor


The voltage to this ignitor should only be 120 volts. If you are getting 240 volts to the ignitor, there is something really wrong with the wiring to the heater or in the heater.

Where is the best place to geta pentair mini max nt 400 control board (472100)?


Best bet is to call Pentair and ask for a dealer that carries the part. Then call the dealer and ask if they have it, can get, what it'll cost etc. Often times local part suppliers won't keep the circuit boards in stock if carried at all. So best to call first. Pentair's number is: (800) 831-7133, andf their website contact info is: http://www.pentairpool.com/pool-owner/contact-us/index.htm
Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave good feedback if you found this helpful. Thanks, and good Luck!

My pool heater will not start. The power light is off and the pressure sw is lit.


You must turn on the pump and let water circulate through the pool and the heater before you turn on the heater otherwise you will ruin the heater
