Very good.

Awesome videos. My Pentair Mastertemp 125 is three years old. It’s only used in summer. Everything thing works great until it reaches the selected temp 90 deg. Then it begins to cycle on and off about every 30 seconds. If I set to 95 deg. Heater will run fine until it reaches the 95 deg. Setting. Then it will start the cycle pattern again. Can you help Thanks 😊

I was wondering if replacing the air flow switch really solved the problem for you. I was working on a mastertemp 400 and I was having the same issues “ignition error” and “AFS”. I replaced the air flow switch but it didn’t solve the problem, I ended up replacing the ignition control module.

Solar heater mat works but needs an independent pump to work better

I've been having ignition issues. I'll have to check this. My heater (same make and model) turns on, fan runs, but doesn't kick to ignite. Then switches to the service heater light.

What causes the ignitor to burn out after one day? Put a new hot surface ignitor on and the next day it's burnt out. Happened twice back to back.

I replaced the gas sensor however it still comes on? The only lights on the outside panel is service heater? What is the next possible option? Thanks

[@user-ms9cb4sq6h]

how do you check to flow and pressure of the LP going into the heater?

[@user-ms9cb4sq6h]

Just answered my own question from one of your other videos. Thank you very much for sharing your knowledge!

Brand new pentair master temp 125 , won't ignite , ignition error on display , red heater lite blinking , I do have a 100 pound propane bottle that the manufacturer said was big enough however , my gas line to the unit has a 10 pound regulator on it , what kind of pressure should the unit receive?

[@w0lf1969]

If you have a 10 pound reg on the tank, you need a second stage reg to drop it down to 1/2 pounds which is max for any appliance

@@w0lf1969 could of used that info a year ago when I asked , got it figured out now , lol

[@w0lf1969]

@scottweedin7570 I know people on here posting stuff all the time but never give answer to our questions. I seem to think they just make videos but don't know what they're really doing
