EXHAUST FAN NOT WORKING

[@JoseHernandez-qc1py]

I am a electrician and went to take a look at exhaust fan in a restaurant as a favor I had the same situation thank you for sharing your knowledge and experience great videos

[@jaymesrod4209]

Chris! You are indeed one hell of a technician, I am glad you decided to make these videos.

[@HVACRVIDEOS]

I'm glad you enjoy them, I will be going live on KZbin this evening 8/26/19 @ 5:PM (west coast time) to discuss my most recent uploads and answer questions from emails, KZbin comments and the Live Chat if you can stop by and check it out kzbin.info/www/bejne/bWnOkmOwodB0iJY

[@NyxKemo]

Your methods don’t only help with HVAC systems but can also help with other jobs like checking everything with the multimeter or turning off the device before resetting something to be able to see if there’s a direct short. Keep up with the great videos

[@JWimpy]

I like your method of trouble shooting. You operate much like I did. I am a retired HVAC tech but I like watching your videos to keep up with what's new in the trade. Although we never totally retire, I maintain my own equipment as well as family members and my church building. Thanks for passing on your knowledge.

It is pretty shocking how many shortcuts people tend to take with electrical wiring. Glad you are thorough and sensible about it!

[@familyhvacheatingandaircon105]

I don't really post a review Buy I've been watching your videos for over 3 months now, and they are very educational and well prepared when it comes to troubleshooting. I'm going for HVAC and it helps me learn between school and out in the field. Thanks and keep it coming

[@dannypilozo3580]

I am electrician I am currently looking at unit with is not working at the moment. Looking at your video show me key points on how to proceed my troubleshooting it. The consumer has it for 9 years.

[@Jshortca1]

I really enjoy your approach to trouble shooting. I am very interested in how you approach the customer when it comes time in your opinion when the equipment needs replacing. I would love to hear how you approach that conversation. Thanks.

[@Ricky32908]

I love your videos! I’ve done preventative maintenance on Publix roofs on exhaust fans and compressors, and evaporators. And condensers and I can say a lot of things like Fan rotation, whether something is clogged or not, can be very hard to tell without knowing the equipment and machinery very well. Good job

[@TheLOD2010]

Nice one. This video shows, why vibration is a cable killer. The construcktion of this electrical part is a bit poor. The can do better. You can make the calbe fittings without sharp edges. The connections straight in line and not 90° offset will make it more safe too. And as a german electrician, I say you do a great job with electric and you show a lot of people how it is made safe and resonsible.

[@kellyspeppers]

[@jarheadshooter6452]

East coast all switches and controls are in weather proof boxes outside the exhaust! The motor connections are required to be properly terminated in a conduit to the external box! It leaves the possibility of a short outside of the combustible area.

That Schneider electric contactor - overload combo makes me feel at home , they're all over the place over here so , nice to see a familiar face 👍

[@johnsmithjr5498]

I was working on an RTU (3PH 460V), I turned the breaker off, I locked out tagged out the breaker, with my name AND cell # on it. I went to get parts. When I got back (the next morning) I had a feeling so I checked the breaker before going back on the roof. Someone had broken the breaker to get my lock off of it and turned the breaker back on!!! Needless to say I was mad and when I found out that the electrician is the one who did it I was Pi$$ed!!! I didn't call OSHA but I did get my boss, his boss and the regional project manager for the general contractor involved!! ALWAYS CHECK THAT THE POWER IS DEAD!! IF YOU LEAVE, RECHECK WHEN YOU GET BACK!! EVEN IF YOU LOCK-OUT TAG-OUT!!! SIGNED, LUCKY TO BE ALIVE

[@walkingfreak]

Pfff 15 year old exhaust fan, at my work they would still keep it going for another 5-10 years by throwing new pillow bearing blocks at em, motors and what not haha.

[@tiredoldmechanic1791]

We had exhaust fans that were installed when the buildings were built in 1966 that were still in use in 2016 when I retired. Put a new belt on every 2 years and lubed the motor and I replaced the pillow block bearings in 2009. Still running on the original motor and it runs constantly. That was for the bathrooms so not all that grease.

[@felixleon105]

Excellent job guys

[@TheColinputer]

That first one was a clear case of 'Oh the fan is tripping? Do we A, work out why its tripping and fix it? Or B, remove the overload protection unit cos its annoying' Give the poor ground that one had and all the grease around could early turn into a fire. Actually reminds me of a friend who too the earth wire off a device because it kept tripping the RCD without any idea about why i was tripping.

[@seanmichael8202]

Those pulleys on the first fan are running opposite directions! How does that work?!! 🤣 Its a trip what tricks the camera plays on your eyes...

If you replaced the the motor sheave, or the motor, do you then perform a air balance check and adjustment in the restaurant?

Where can I find parts for a magnetek motor? I need belts as well. The old unit was marked mcquay, but the permit from the 1990s says the fan is a Jenn air. Is there a good parts website?

[@HVACRVIDEOS]

Your probably gonna need to find a wholesale house or a motor supply house local to you

[@bigblockelectra]

@@HVACRVIDEOS ok thanks

[@tyhuffman5447]

Good safety tips, look for electrical faults first then start turning things on. something like a grommet would help keep the wires from rubbing on sharpish metal. It appears to my thinking, normally wrong, that the air flow off the exhaust fan wouldn't be past the motor. That would be pulling greasy and smokey exhaust past electrical equipment. The first Ex.Fan was a total mess.

[@ren3gade__]

Just had a service call with exhaust fan going on then off motor super hot!! off on overload, once cooled, reset run for little time then off. Belt tension was too tight causing over work. I have adjusted the tension and have been running well; no issues since.

[@treverkirk8110]

Really need to get an overload on that one exhaust fan! that motor could catch on fire before a breaker trips, especially with all that grease.

Hey Chris May be a dumb question but I don’t work on vents at this time but what controls the motor starter? I’ve poked around a few of the kitchens and see basic switches the cooks turn on in morning. Is that all that controls the starter(contactor)?

@ 3:10, metal box/switch isn't grounded well enough to short and trip breaker, lucky you or the manager that touched the thing didn't get zapped taking it off/on or create a fierwork/welding show via the unit and ducting or ignite the building on fire, possibly between the ceiling and roof even. yikes ** and you covered that shortly after in the video lol. yeah I like to comment as I watch, more so since youtube has been eating long delayed comment/videos watching. got tired of it eating them and "edit" works ok I guess

I have a question... when i fan exhaust not take out all the smoke... is posible to intall in it a bigger power motor for fix it o is not possible...

[@HVACRVIDEOS]

There are several things that can cause it to not take out the smoke. it may be undersized but also it could have a loose or broken belt, it could have broken duct work, and or your building could be out of balance.

Great job .

[@retake1697]

I brought a DAYTON 4YC67G two years ago, and it stopped circulating any air in the vent. All I hear now is a low humming noise and it cuts off every 2mins. Any advice would greatly help thanks. I was wondering if i should vacuum inside the duct vent covers.

[@zspacecaptain8228]

It sounds like a stuck motor that its cutting out from overheat. Try opening it up and checking if anything is jamming it. Vacuuming inside the vent covers probably won't help, but you should do it every few years or so. If the motor has a starting/running capacitor it may be bad, but the only way to check it is to either change it or use a meter. If none of that helps you may need a new motor.

[@neutrodyne]

Are the new fans all direct drive or do they still make them with drive belts?

[@HVACRVIDEOS]

They can be either way

[@PleaseExplainMe]

Are you sure this are motor starters? I know them as thermal overloads .... And is it still standard to put a belt driven exhaustfan on a building? Here in the Netherlands, we are using direct drive fans since the 70's ....

[@inuyasha32]

To be exact in the united states a "motor starter" consists of 2 parts the contactor and the thermal overload, this can be in 1 component or like in this video separate components, the thermal overload had been removed with the contactor remaining here.

[@grindstone5368]

See direct drives on smaller hoods never seen them on the larger ones, I'll have to check that out...and I still run across fans from the 70's😂🤣

[@PleaseExplainMe]

@@inuyasha32 Okay, the most basic version of a "motor starter" here is a star-delta configuration (or star-double star for 2 speed motors)

[@lwilton]

Hum, do you want to consider re-editing that bit on the rotation of the second fan? I think you meant to cut out that first try where you got the rotation description backwards.

(1st fan)maybe it had shorted en previous and they reset the beaker and it didn't trip the second time cuz the metal case and copper wire had melted away, now when the fan came on there was such a high resistance in the the other two phase wires(due to the copper melting away) that the voltage drop on the other phases was so high causing the motor to run hot as it was mostly running on one phase
