No Heat Boiler Won't Fire Munchkin F09 Lockout
HTML-код
- Опубликовано: 12 сен 2024
- I am on a no-heat service call and the boiler won't fire up. I test it a few times and it won't fire up for me. I notice the boiler's swirl plate was deteriorating. I pull the burner to verify the burner tube condition is good. I also tested the spark plug. Once I pulled the fan off I found the swirl plate was busted worse that I thought.
exactly why I wont be installing a complicated high efficiency boiler... Good vids!
I been saying that for years. I bought a house that doesn’t have a chimney. The boiler uses an inducer and vents side wall. I noticed a lot of rust under burners. Most likely condensation. If I had a chimney I wouldn’t consider a hi efficient boiler. Hopefully I don’t have to replace this boiler for some time. I should most likely do a good service on it, just been too busy with working on he garage
Mine had this problem. I had an hvac guy out to diagnose. They told me flame sensor. I swapped it and it didnt work. They told me if not flame sensor- then control panel. I didnt fall for it. Loosely wrapped a dish towel around this part to allow less airflow and it fired up the first time. Amazing this little piece of swirling non mobile plastic was their engineers answer to proper air flow- then again my unit is 16 years old. The part is disintegrating. Thanks for the video- helped me immensely.
I solved my 140M problems (F09). Here's the key: make sure the NIT screws are removed and shiny clean with a wire brush for each maintenance. This ensures proper grounding. Also, make sure the exhaust and intake are properly separated outside. If not properly separated, exhaust gas is pulled in and chews up the swirl plate, and throws off combustion. I added an extension to the exhaust. The original specification for intake/exhaust separation may not be good enough. If one stays on top of the maintenance, these boilers run very well!
Have turbo water heater at work that has same set up but plastic swirl. Had to replace twice in 5 years do to busting. Course you have to replace the whole part, not just swirl. Thanks for posting.
I can get individual parts for this boiler until parts vanish. The company that made this boiler went bankrupt
Hey Bill ya can’t end the video until ya show the fix and how it runs afterwards. You definitely found the problem I would say. Nice work
I prefer to go back and complete my repairs. I had to hand the parts off to another tech. I was locked up on a maintenance in a 30k sq ft home and couldn't hand that maintenance off. Too much wasted time. It would take me two hours to show my coworker where everything is hidden. Due to a coworker not noticing the swirl plate deteriorated. I should still post this so other techs, hopefully catch the plastic breaking down on that swirl plate. Before it causes failure.
@@thehvachacker much appreciated if you do.
I had this issue before, you need to pipe exhaust above intake and the max distance of 3 feet. If not you will recirculate corrosive exhaust gas back into intake and the swirl plate corrodes like in your case
It’s exhausted correctly. I seen this code way too often. A plugged drain will kill the flame signal, swirl plates also dry rot on their own, bad electrodes, dirty rods, possible exhausted incorrectly. Yet if exhausted incorrectly and drawing back in exhaust fumes all the gas gets really rusty and aluminum also gets signs of corrosion. Munchkin been out of business for over 10 years. Back 2005 I use to hate running into these. Usually busted plastic blower wheels
Bill. It’s. Edbonjovi. That was. A great. Find. Nice job. Good. My. Man. Good. Luck. Finding. That. Part. On. The. Self. Lol. Hope. All. Is. Great. With. Your. New. House. Eddie. Leak master. Plumbing. Have. A. Safe. New. Yr.
Have a happy new year. I just recently worked on this boilers green brother the Peerless Pinnacle
Boiler sounded like a truck "jake breaking" past my house because of this issue. $33 part at the time. Plumber charged me $700.00 and failed to fix the issue. Found and fixed myself after reading parts diagram and talked the bill down to $200.00. They did after all do some routine maintenance. A few days later the noise began again and my heart sank. Turned out to be an actual truck "jake breaking" past my house from a construction site above. They are no longer permitted to do this without being fined $$$$$.
Happy new years
cast iron 80% is looking better and better.......
Yes cast iron boilers don’t have all these little finicky parts
Hacker is that like an inducer motor blades? Peace brother
That’s considered a blower motor, the swirl plate is to regulate the air fuel mixture. The blades are inside the motor I have a video that I just need to edit out the dead spaces with a problem blower
What is model of the munchkin boiler ?
Do you have a video regarding the loose ground from the rectifier? I had this issue years back. When the ground was tightened it worked for almost three years. Starting to act up again.
The Great Hacker is in the Land Of OZ working a Munchkin boiler . He followed the yellow brick road and found the wicked witch of the west had destroyed the boiler. The Hacker finished the job an clicked his heels together and woke up at his new house!!
Nice job
U like that old style manometer?
I prefer using the Magnehelic gauge over the manometer. I am giving a digital manometer a chance, Just got this one. The around the 8-minute mark the true response of the gauges shows ruclips.net/video/WjS0WuxSD6I/видео.html
I had a nat gas boiler system on a low pressure main and customer got water up inside meter. The inlet gas pressure would change soo fast because of water blocking inside gas meter then making pass water that a digital manometer couldn't pick up the change in pressure. So it's good to have the old analog gauge sometimes. I do own two digital manometers as well.
JJ check the vid link on my comment to Nathan. Its on my other channel. It shows the response rate difference. The digital manometer I just bought wasn't cheap, yet at least i can adjust pressure switches with it. I am going to give it a chance. What made me stop using digital almost 10 years ago I had a gas gun that was acting up. It was an oil boiler converted to gas. The pressure switch was .15"w.c. The air baffle wasn't opened enough. The digital made me believe it was the pressure switch. I returned with switch. Still didn't work. The analogy showed the fluctuations causing the switch to open. All i needed to do was open the air baffle one rotation.
I use Dwyer digital manometers. Very fast response time.
Do you need to drain them or no. Thanks
No need to drain a hot water boiler. A hot water system fresh water introduced should be minimal. Steam systems require the draining since it’s rust from inside the pipes, radiator and boiler that forms mud at the bottom
@@thehvachacker thanks I may need to open one up. Love ykur videos. You show the real deal.
I do the same type of work. My other company did generators amd they did not do what you do keep them coming
Many companies don’t charge enough for the generator service to go into detail like I do. We have 3 hours of labor factored into the maintenance plus kit.
The munchkin has a busted doughnut... looks like a sour cream doughnut
Glue it back together with some Gasoila dope you hacker
How is your gas pressure good? Natty has 3 1/2
Propane 10-12
7” w.c. Going into gas valve. It’s a negative pressure valve. That’s not an inducer motor. It’s a blower motor. Their was too much air being mixed due to the withered away swirl plate.
Your company install these?
I’ve taken a couple of them out never serviced one
Use to years ago. Until we switched to lochinvar boilers. These were the high end boilers 2002-2008. Yet turned out they had lots of problems
A short one, turbo bad it looks like. haha
It’s like a turbo. It forces the air and fuel into the burner. Also ramps up and down as needed
Munchkin? This is why I push readily available appliances to customers like Navian and Lochnivar and Rianni boilers. No exotics.
Lochinvar stole their technology from munchkin. Munchkin was first to this space yet somehow went bankrupt. This boiler is from 2006. Lochinvar just took munchkins technology and made a better boiler with it.
Yet parts are available just not as easy to get like the Lochinvar. I wasn't knocking Lochinvar boilers. I think they are great and might install one at my home
Yep munchkin no longer so tough to find parts at times. They issues with heat exchanger if I remember correctly
HTP bought them up and honor warranties. The munchkin had a lifetime heat exchanger. When i have a leaking heat exchanger i tell my customer to contact HTP. Some have gotten a boiler and we install for them.
@@thehvachacker that's good to know .
What does a swirl plate do on thise munchkin boilers?
Restricts air also helps the fuel and gas mix correctly for the burner
First (for once)
Always good to be first
