Terribly Designed Heat Pump Split System Having Low Volt Issues | HVAC

THANK YOU 🤟 😎

[@TomLawson05]

That must be a jerry Lee lewis unit hole lot of shaking going on good repair thanks for the video

Shaking more than Jerry Jones watching the Cowboys lose to the Detroit Lions ✊🏽

If you hit a fuse with sand paper, the connection will be fresh. Aluminum car odes. 😊

[@AB_HVAC]

The fusible link piece snapped in the middle, no sanding would've fixed that but I get what you mean

[@jkmarshall3553]

Nice find with the wires! You think that attic was low, you should see mine. I have no idea how they got the evap/blower assembly up there and I just hope it runs forever bc I don't have to mess with it. 🤣

@@jkmarshall3553 I can't stand when the unit is facing the opposite way I came from. Climbing over that thing was not fun

Good video, Heat Pumps and Mini Split systems are Gods joke on the HVAC trade. I think what happens to a fuse is that every time there is a surge of current flowing through a fuse just like wire over time it can weakens the internal fuse. I'm sure electricians will say it won't happen , so to hell with electricians.

😅 I don't too much mind heat pumps if they are installed in a dual fuel operation

[@john7017]

The blower vibration may come back to haunt you. Sequencer relays do not like vibration, hope it does not come back in. That install wound not pass inspection in my State do to improper access, decking around unit, lighting, lack of receptacle. Horrible install plus leaving junk up there...

[@AB_HVAC]

Yeah it actually amazes me at how these rentals pass any type of inspection. They must have an inside guy

[@deanmartin1966]

Never did see if the heat strips came on. Did you check the coil on the contactor for the heat strips? Imagine that would be popping your fuse. I saw the outside heat pump working. I would’ve told the landlord that blower motor has to go. But I also know how they’re cheap and don’t want to spend any money.

[@AB_HVAC]

I didn't see it come on at all but that's because the thermostat wasn't kicking it on I know normally about 2 or 3 degrees higher than setpoint Aux heat should kick on it never did. Someone else mentioned a time in the video where they noticed a burn mark on the contactor for the heat strips but I missed that. Due to my location most people never have their heat on anyway so I never thought of the idea that the heat strip contactor could've shorted. Not to say it isn't possible I've just never come across it

[@deanmartin1966]

@ That’s probably why they never came on. The contactor coil for the heat strips were probably shorted.

[@AB_HVAC]

@deanmartin1966 yeah. I'll own up to that callback if that's the case. I was really hoping it was the exposed t-stat wire 😅

[@jes6885]

Weak intermittent contactor coil??

[@AB_HVAC]

Eh, I've never seen that so I wouldn't say it's impossible. I probably could've checked the coil for the heat strips looking back on it

[@jes6885]

Happened to me on the same exact unit. Electric heat contactor coil was melted/burnt. If you go back to the 4:45 mark you can see a black melted/burnt mark on the coil , i had to look back lol most likely your issue

[@jes6885]

Look up melted contactor coil on google image and you’ll see what im talking about 👌

[@gordonpotts753]

That's bull shit that u have to put up with those working conditions.

[@AB_HVAC]

I wouldnt have minded the walk to the unit if i didnt have to crawl over the unit.

[@warenmann1042]

What is that vibration, did a three year old get up there and hide his teddy bear in the evap fan. Bad install. Good diagnostics. Good job...

[@AB_HVAC]

🤣 idk man but I think that's why someone was putting bricks and stuff on it. It shakes the load bearing wall in the house

[@warenmann1042]

@@AB_HVAC The evap fan shaft is bent or cage out of balance/round. They just didn't won't to replace it. Vibration is bad for fuses and other a/c things like evaporators, so expect more failures. You just might get the chance to replace the air handler As a homeowner I would complain.....

[@AB_HVAC]

@warenmann1042 unfortunately these property managers just want the unit running. I can barely do legit preventative maintenance on these units because they're so cheap. Some people will live in these homes for years and tell me how people only come out when something breaks

[@warenmann1042]

@@AB_HVAC Not blaming you, just saying, I understand about Property Managers...

[@AB_HVAC]

@warenmann1042 they're definitely a piece of work 😮‍💨 could hear the shaking from outside
