Question about Hayward H Series Induced Draft Abg 100,000 Heater

1 Answer

H100id induced pool heater runs for 4 minutes then stops heating

I jumped out both limit switches, and the water flow switch. It ran for 2 straight days in this condition then today it stopped heating again. The blower continues to run, the ignitor is getting spark. Could this be the thermostat? When i adjusted the thermostat setting to about half way it started to run again and has been running now for about an hour.

I just solved this about an hour ago. It's the connection from the circuit board to the ignitor. The same thing happened to me that it ran a long time and then it wouldn't. At some point it loses spark. The large wire from the board to thee= ignitor is the culprit. Take the ignitor out and press the two electrodes to about 1/4"-3/8max. Clean the surface plate where it meets the heater and also clean the brass piece on the othe end. Then clean the brass piece on the circuit board. Slide the 2 boots down a little and expose the receptacles. Press them a little with pliers, put them on their respective connections and then slide the boots back on. It started right up and has been running since! This after I bought a new gas valve $178! Let me know if this does it for you.

Model # 5vp40e-1 Richmond power vent hot water heater made some ticking noises very faint and stopped heating up.fan does not run either.


First try turning off the switch, unplugging it, replugging it in and flipping the switch to restart it. If this doesn't work, the first thing I would check is the draft inducer(looks like blowdryer) and the pressure switch which looks like a flying saucer. If you flip the switch, the first thing you should hear is the draft inducer blowing. If it blows and then stops, jump out the pressure switch and try to relight. If that works, it's the pressure switch.Replace it. There are other safety devices like roll-out switches and hi-limit switches that may be bad. Also, your flue pipe could be clogged, or your vent on the draft inducer may be clogged. Those will set of a safety switch because of overheating. That may be the ticking you were hearing.This is especially likely if your water heater is located in the laundry room because of all the lint floating around. If you've never troubleshot low voltage electric circuits before, you are better off hiring a service mechanic.

Since the heater fires it sounds like it could be the bypass valve stuck open. The bypass valve allows some of the water to enter the heater, while the rest bypasses the heater and returns to the pool.


If the bypass is stuck open, or broken, it allows the vast majority of the water to bypass the heater and continue to the pool. The water that is in the heat exchanger will become too hot due to slow flow and activate the high limit switch, turning the heater off.


The bypass is located where the pipes attach to the heater and can be checked or replaced if needed fairly easily.

LO error message on heater. Everything shuts off after a few minutes of running.


On of your limits is not working or not wired up. An easy way to check the limits - Water pressure switch, Hi limits, air pressure switch all of which have 2 wires going to them. Unplug one item and connect the 2 wires together ( paper clip works fine ) Then retest, if problem does not go away remove paper clip and reconnect wires and move to the next limit. Always make sure water is flowing through the heater at all times while checking the limits.

Pool heater fires up and starts heating the water outflowing into the pool, but only stays warm for 5 minutes or less then cools and stops heating


You are tripping a temp limit switch. You either have a bad switch which you can jump the wire to confirm. This is a trouble shooting technic only. Jumping the wire permantly might cause bigger problems.

HAYWARD POOL HEATER FIRES FOR 5 MIN. THEN GOES OUT


Sounds like it is cycling on high limit; causes are related to water flow through the heat exchanger or a faulty high limit(doubtful given the heater cycles back on). Check the internal bypass for obstructions; has anyone worked on it recently? There are usually two high limit switches with different trip temperatures; installing the wrong one could also be the culprit. Does the heater "bang" before it goes off (a sign that the water is boiling inside the tube bundle)?

I had a similar problem and it turned out to be the solder connections on the control module. The connector that is soldered to this board (comes from the gas valve) needed to be re-soldered.
