    Pentair MasterTemp 400 Heater Won't Light

    Just to follow up, the hammer part was levity. Typically when a coil operated valve starts buzzing, you change it out.

    But he forced the contacts closed on the power relay output that tells the fenwal that all sensors are good to fire up heater. So, no, there is no control logic anymore.

    Another.....Mastertemp 400 with AGS LED + Service Heater LED

    I believe if he had a blower failure, the gas valve and ignitor would still fire. This can be verified by disconnecting the air pressure switch and start the heater. Maybe if he had a filter pump failure, the heater would continue to fire. This can be verified by disconnecting the wires...

    Another Pentair MasterTemp 400 won't stay lit, AGS Error Light

    Pentair had an update last year. Basically, if you replace the control board on an older heater, you need to buy a six button membrane pad to work with it. Some vendors are selling both as a kit. If you are just replacing a membrane pad on an older heater, you can still replace it with the five...

    Suction Side Air Leak - I give up

    Than if you find the leak is due to a fitting that wasnt glued properly, while running the pump, use clear primer and daub the pipe joint, than repeat with clear pvc cement. Do this twice. It will be sucked into fitting making a permanent seal. Leave system run for a half hour before shutting off.

    Issue with my Pentair Mastertemp 400

    From your photo of touchpad membrane, you have a six button membrane attached to a six year old heater that came originally equipped with a five button touchpad. I assume your pool guy did that when he replaced your control board. Thanks to your photo, I researched and found out that if someone...

    Pentair MasterTemp 400 Heater Won't Light

    While its buzzing, give it a sharp rap with a hammer. Wonder why Swamp didnt advise this first. Insider trick. Time to change it out. Let Pentair know, if its a package with two other Pentair products, its covered under a three year warranty. Check the orifice for debris. Have the gas company...

    That power relay is different in rev 14. Need to make out part numbers on originals photo before it had its top removed. And the original relay may have been ok. Need to remove it from circuit to test. Or unscrew board and put a voltmeter on pins that connect to coil and see if its getting rated...

    EasyTouch 8 with VS Pentair Intelliflo random shut off in Spa mode only

    Try programing your pump to run at 2000 rpms while in spa mode. I know that the pump isnt supposed to cycle with the heater overtemp, but somethings crossed up.

    Pentair Whisperflo frozen ... found crack

    Invest in a cheap home depot tarp and a trouble light with a 30 watt light bulb which will keep the pump housing from freezing again after your repair.

    Propane Tank Noise when heating hot-tub.

    When the tank is making that noise, go over to tank and put your thumb over the regulators vent opening, its that horn shaped part with the screen inside. The noise may stop for a while. The regulator needs replacing. If you rent the tank from the gas company, they are responsible for replacing...

    Removing pool light power

    The gfi would protect you by tripping almost instantaneously if a fault occurred. I should know, I fell into my pool with a running 120 v leaf blower plugged into a gfi. Not only did it save me, but after drying out, the leaf blower was good as new. Gfi protected outlets are more than a...

    Pool Company Telling me to connect Motor to 240 Volts for Longevity

    The giant regulator is actually the governors of the steam turbine generators at the power plant maintaining a constant rotor speed. As load increases, generator rotor starts slowing down due to increasing flux fields, which causes governor to admit more steam to generator turbine to maintain...

    Propane Tank Noise when heating hot-tub.

    If the noise sounds like a horn blaring, it is going to be the propane tank pressure regulator that sits on top of the tank. There are rubber diaphragms inside that need servicing. Most propane suppliers do not fix these reguators, they just replace them. If you are renting the tank, call the...

    Newby questions - CH for "winter" in Charlotte, SWGs, Valves, Heaters, Oh My!

    If you are running your vs pump 23 hrs a day, I assume you have your pump speed quite low to save electricity. I don't have a pressure side cleaner, but the name implies how it is designed to operate. I also assume the manufacturer has installed flow restrictors that must be adjustable. I also...

    Can "dirty" SWCG cell impact pressure to water features?

    You state that your pool was built this past summer. I would call builder and have him send someone to check it out. A lot of times they do sloppy work with the plastering, and pvc lines get partially plugged and need to be cleared. I was picking out plaster that was almost golf ball size from...

    My pool builder had his electrician wire my intelliclor hot all the time. After reading the Pentair literature for the swg, I switched the power supply feed to the filter pump relay, ….it also stopped that annoying flashing lights. lol. I guess the electricians know better until they learn...

    Pentair QuickTouch II wireless remote losing connection.

    I had a problem after installing this unit. Called Pentair but got a new tech who didn't know the circuit well enough to troubleshoot. If you are having an intermittent problem, the answer may be the fifteen ft of 24 wire gage that comes with the remote. Its so tiny that it can break when you...
