The red low temperature light went on on my IC 40. This seemed unusual as the temperature of the water was about 80°. It was my guess that the thermistor had gone bad. So I replaced the flow switch and everything operated normally for several weeks and then the light went back on. I replaced the...

I found one for just under $400 and felt that would not break the bank. Pentair has plenty of my retirement savings already. They should have a retirement plan.

I have a surge protector that I can install on that ethernet connection. Been thinking of doing a Whole House unit, lightning is rare here but surges are not.

Here's an interesting link right here in TFP https://www.troublefreepool.com/threads/fiber-optic-pool-light-conversion-to-led-less-than-100.239691/

I did all of that this morning. I'll report back when I've had it running for a day or so. Yesterday I ordered the ScreenLogic device. I have ethernet in my pool room so I won't need the wireless part.

There is no schedule associated with. I think what I’m going to do is delete this circuit and then start over again using a different circuit and see if I get the same result.

If you still have the light, I can repair it and make it work for you.

I do not have ScreenLogic. But I can tell you that I have two schedules for my pump. Could that be triggering it?

With the WhisperFlo VST I programmed three speeds. One is for 3,000 RPM for when I run my vac. I have an open button on the Panel in the No.6 position. From the Names List I chose to rename this to ""Bottom Cleaning". From the speed setting I chose the Circuit "Bottom Cleaning" So when I press...

I found this, it is the correct item and even has an excellent photo. Onlinepoolshop.com : Pentair 21003700 FIBERworks UltraGlow 25 Perimeter Fiber Optic Cable, 200-Feet I guess I need to find someone who has substituted something that is working. Do you know anyone who has persevered to find a...

I don't have screen logic, thinking about it, though. It's a lot easier to understand than the EasyTouch 8 control panel! Thank you for your help!

Has anyone turned up a source for the original or a new version of the perimeter fiber optics for Pentair Fiberstars system? I do repairs and restoration of the head units yet have not been able to unearth a source for the fiber optic cable.

I want to program my WhisperFlo VST through the EasyTouch8 controller. I have all of the pump connected through the Com port and working. Question 1: How can I program the pump to a certain speed when the pool is calling for heat? The pump is set to run at a 2,250 rpm for most of the time. It...

I am looking for a source to replace Pentair fiber optic rope lights. The fiber part is OK but the vinyl rope is starting to alligator and turn brown. I have repaired the light source and that all works well. Ultra Glo

I live in an area where we have a lot of stuff falling out of the sky and into the pool, particularly the cotton from cottonwood trees nearby. In the past this stuff is sucked into the filtration system and gathers on the cartridge filter. It can even germinate on the side of the filter. For a...

Finding it difficult to locate a 300K BTU heater I brought in my gas contractor and he told me my service would support the 400K unit. He will do the gas connection and replace the regulator valve. I was able to find the unit on Amazon and they offered me a three year warranty. I will respond...

I am replacing my MasterTemp 300KBTU heater. Can you suggest a thread about this and the virtues of DIY versus "Certified" installation along with warranty implications?

I am using an EasyTouch 8. It's also vintage 2007. I have the EasyTouch Wireless Control Panel but when the mother board in the panel went bad and I replaced it the Wireless Control would no longer communicate with it.

I did a bit of exploration with a screwdriver and found that the cover for the heater, 42001-0214S, as you suspected, is toast. Thank you for your help in this matter. Pictures were very helpful for getting to the bottom of the problem as you know! I did check on the part and it's no longer...

The combustion chamber is solid. The corrosion on the lid is superficial and could be removed. We seem to have narrowed this down to an issue with the flame sensor circuitry. Since I am understanding that the igniter is part of the flame sensing circuit, and I've just replaced the igniter, would...

Where is the flame sensor located?

The tub is dry as a bone, no water came out when I removed the bolt. Is it possible that when I installed the igniter the gasket didn't seat properly? It ran for two days before this problem arose. I checked out the two videos of the heater core replacement. This components appear in much better...

I haven't detected hot air inside of the heater cabinet and I've been all over it looking for issues.

I removed that bolt and it's dry and no water came out.

I installed the ground wire between the flange and one of the flange screws as pictured in the first two photos with no change. Then I started over from scratch and installed it between the flange and a grounded screw in the box that contains the Fenwall as shown in the third and fourth photos...
