    Hayward H300 Heater Help!

    I did notice that as well. The resistors themselves are not obviously damaged but I'm going to look into any repair options available as I can't find this board anywhere. The control panel assembly is HAXCPA3301 which I assume includes the board. I'm not sure how feasible repair is but will...

    Wow...so maybe I do have a board issue. I only see one. Pic above. Now let me see what that would cost relative to a gas valve and do I dare fix that first. Thanks so much for your support. 🙏

    I performed the test with the wires disconnected. The 27V showed up very quickly - not more than a second I would think. I'm not sure what the time should be. I wish there was a way to unstick this solenoid? Tapping with a 🔨 didn't help. I can't afford a new valve right now which seems to...

    I redid the voltage test at the gas valve and it did quickly jump to 27 (not 24) and then quickly back down. So, I think gas valve is bad 😞.

    I also tested resistance at the gas valve and the reading was 20 ohms which I think may be low for a gas valve...hmm

    I think I have checked voltage at the gas valve and it is low. I connected my meter to the Orange wire disconnected from the gas valve. The starting sequence initiated and the ticking still occurred but much quieter. The meter only showed about 2.0.

    Yes, I put my hand on the valve as it's trying to fire and I can feel it vibrate and make a louder clank but no light, no gas smell.

    Despite numerous gailed attempts through firing sequence, I smell no gas. Could I be so lucky to have both an ignitor issue, which I fixed, and a gas valve issue at the same time?? The clicking noise I thought was the spark on the ignitor arcing across the ignitor.

    I am not sure if ignitor is hot surface. Attached is a pic of old one. I wish I could attach short vid of the sound. Basically a repetitive clicking and then a louder click but no fire up. I double checked gas is turned on gas valve is set to on. I am not getting any error codes since...

    Hayward H300 Heater Help!

    I recently noticed my pool heater had an IF error code. I tested the ignitor and it was bad. I replaced the ignitor a week later when part arrived. Heater off for the week. Now, I can hear it clicking which I assume is ignitor sparking but it still won't fire. There is no more error codes...
