Yep, EXCLUSIVELY when it's actively heating. When active heating = constant smell of gas from exhaust, all else = no smell from anywhere.

Thanks poolman. This odor is sustained and present in the exhaust only even hours after start up.

Great info so quickly, thanks all! So the only relevant component that would have changed since the power incident (and when I did NOT notice the gas smell) was the blower/fan. I did replace this item with a used part that came off the same model that had another issue not related to the blower...

Thanks! So - it sounds like there is no way to access the burners; does that also mean there's no way to control the gas/air mix?

Hello all! A little backstory; earlier in the year I had an electrical situation that ended up frying multiple parts on my Jandy XJI heater. I replaced the power distribution board, power transformer, Fenwal ignition control, and the blower motor. The heater worked like a champ all season and...

Heater FIXED!!! Just in case anybody is interested or if anybody with the same issue stumbles upon this thread - here’s the deal. FUN FACT: A blower motor can run just fine tested wired 120v but not at 240v as it’s wired when connected to the heater. Not sure if this means the internal wires...

I probably could, but I honestly can't make sense of how that would need to happen... I've studied the motor wiring diagram (attached) and I can't figure out what wires to send to the plug. I THINK what I'm seeing here for 240V is get a 120V hot to RED, then another 120V hot to BLUE/YELLOW...

Wired 120V, flipped the board, exact same behavior. Single blink, no blower. I'm going to have to bit the bullet and replace the blower and hope it wasn't $700 of wasted money, or call a pro. UGH!

That's a great idea. Flip the board and wire it 120V from a power cord directly to the red/black/green on the PDB. Just wondering though, if changed to 120 - is the blower fan going to run at 120? The fan connector clip will still be connected to the PDB and wired as it was; will it just "work"...

My soul is getting crushed 🤣 Received my Fenwal in the mail today and it didn't resolve the problem. It was however necessary to replace, since I could never previously get 120V at both F1 and F2 to power the other 120V leg of the 240VAC blower. NOW F1 and F2 to ground BOTH test 120V so I'd say...

You guys really are the best. Everybody here has been so incredibly helpful and friendly, can't thank you enough. I ordered a new Fenwal and am hoping that does it. In the interim - I'd really like to more confidently exclude the blower fan. Even though I had it running with a 120V extension...

Makes sense and thanks. Pretty sure I'm doing it right (although I am a novice)... Using either the resistance (ohms symbol) or audible continuity (volume symbol) on the meter, one probe in the female F1 and the other in the female F2 directly on the Fenwal. Observed through all stages of heater...

I'm getting no continuity between either F1->F2 or from ground->F1 or ground->F2 with the multimeter in any state of off, on, starting up, etc. Is this a slam dunk for bad Fenwal?

When I bench tested the blower motor, I only used 3 of the 5 pins in the harness (white to neutral, yellow to hot, green to ground). The harness DOES have 2 pins that appear to have been burnt in the initial incident; but I sort of excluded the blower motor after it bench-tested OK since it did...

Thanks! The Fenwal visually looks OK and I do hear a small 'click' a few seconds after powering on the unit which I recall happening just before the blower would kick in back in the good old days when the heater was working... Not sure if that means anything or not.

Update! Good and bad. Good: Replacing the transformer (and PDB) fixed the shorting and no power issue - so now the heater powers on without tripping breakers or any fireworks. Bad: It now shows a single blink on the Fenwal (air flow fault) and eventually/sometimes “Fault check ignition…” on the...

Hey Chris and thanks for the reply! I can definetely give the multimeter route a go - good info! The heater had never been opened before this incident, and the voltage selector card was correct in the both the original and the replacement card that both burnt up (240V facing down towards the...

Hello! OK, so I'm learning a lot about my heater and since it's been HOT here in Michigan I thankfully haven't needed it. Anyway - I removed the blower motor last night to inspect it and bench test it assuming I may have to replace it anyway. I could find no evidence of short int the wiring...

Thanks poolman. I follow and will do... I truly like to try and learn while being safe and thorough - BUT if I strike out I have nothing against calling a pro. It certainly may come to that. I fear this could be the blower, I checked resistance with a multimeter and got unexpected readings of 0...

PS: If it helps, here are pics of the transformer. Not totally sure what I would be looking for if "good/bad" is possible on a visual...

Hello all! I'm suddenly having a problem with my Jandy JXI200N natural gas heater which is about 4 years old. I noticed the pool pump was off when scheduled on, and ultimately found a tripped circuit breaker. Flipping the breaker restored the pump but the heater remained OFF (yes, the pool...
