    Pentair MiniMax Plus 400 - Pilot light works, burners don't fire

    It looks like the corroded connection is the MV (main valve power) connection. PV=pilot valve power and MV/PV= common power connection. It looks like the male spade connection at the gas valve is corroded off. Due to the excessive corrosion of the gas valve, just replacing the gas valve may not...

    Hayward Heater - Gas Valve - Why Do These Fail?

    If the gas valve solenoid is sticking closed when voltage is applied, you will draw more amperage than the listed amps on the gas valve label and might blow a low voltage fuse. If the solenoid coil is open, you will show 0 amps when the gas valve is powered.

    Flooded heater - safe to try and turn on or no?

    If it did submerge the heater I would also include any and all electronics, safeties and wiring connections. Feel free to ask any questions of our experts here regarding a new heater.

    Flooded heater - safe to try and turn on or no?

    If the water level reached the height of the rust on the outside of the AC condenser it is likely that the gas valve, inline regulator and some heater safeties were in the water and these should be replaced in order to run the heater safely. This is true even if these parts were only partially...

    Raypak Electric Heater “Comp Start Delay

    Regarding the high-pressure trip/lockout, the water flowing through the heat pump from your pool is what reduces both the pressure and temperature of the discharge gas from your compressor and causes it to condense into a liquid transferring the heat to your pool water. Low water flow from a...

    MasterTemp AFS Error

    If your heater is running the AFS contacts are part of an electrical circuit and you would be measuring voltage not resistance. If the blower is not creating adequate differential pressure either to close the AFS contacts or keep the AFS contacts closed, there can be numerous causes for that.

    MasterTemp AFS Error

    There are only 2 choices when you have an airflow switch problem. Either you are developing the correct pressure differential to make the switch close and it isn't closing (failed airflow switch) or you are not developing the correct pressure differential to close the switch. A differential...

    Ray pac 266a heat exchanger issue.

    Difficult to tell without seeing all of the parts both inside and outside of the burner compartment, but from the excessive amount of corrosion it might not be due to a water leak from the heat exchanger/water manifold. You could try running the heater with the gas supply shut off to see if you...

    kool deck resurfacing

    Ended up getting all of the old removed, etched, rinsed, coated and colored. and then sealed for $ 3000 (just under $6/sq,ft. Crew was very detail oriented and left everything very clean. Looks great! I might have them clean, stain and seal my concrete patio next.

    kool deck resurfacing

    I have a 20-year-old pool with a type of cool deck in Las Vegas. The decking was showing wear and deterioration. During covid I had a company attempt to do a repair and it turned out badly. The parts that they repaired looked good for about a year, but are now showing ugly wear in the repaired...

    Help diagnosing Jandy LXI heater, Ignition fault error, Fenwal air flow fault with single blink red LED

    So you are saying that the "IGN/FS" and the "PS" wires are switched at the Fenwal? In that case you would be putting 24V from the closed contacts of the pressure switch to the flame sensor circuit which is not active until the end of the sequence of operation when the Fenwal checks for flame...

    Help diagnosing Jandy LXI heater, Ignition fault error, Fenwal air flow fault with single blink red LED

    You said that you get a 1 blink fault code at the Fenwal. That is an airflow fault code and you would not start the ignition sequence by putting 24V to "PS" on the Fenwal and powering the ignitor for the 40 sec warmup nor get 24V between "VAL" and "GND" after the warmup.

    Help diagnosing Jandy LXI heater, Ignition fault error, Fenwal air flow fault with single blink red LED

    How did you test the airflow switch? With a differential manometer? If the blower starts up, you should have 24V between "W" and "GND" on the Fenwal. If you then don't have 24V between "PS" and "GND" on the Fenwal, either the pressure switch is not closing because of insufficient airflow (...

    Hayward h-series low nox pool heater - Gas

    You are showing both sides of the connections for the 2 wires (at the connector for the "fuse circuit board" and the "control module"). It appears to be burnt off at the 2 pin connector to the "fuse circuit board". The fuse circuit board part number should be FDXLFWP1930. The 2 wires are the low...
