prob wouldn't change much either way but shut the bypass damper... Done

I had a make-up air keep tripping about once every couple weeks or so. It had the internal breaker switch on it. I thought great this oughta be fun, but to start I put a new 75va xfmer (orig was 40)...

Don't count out the possibility of getting another bad board, if it were me I'd get another board and the harness. I also wouldn't count out the module either, maybe with the harness being plugged in...

Get a meter with a mfd setting, you wont look back.. My fieldpiece does it and their not the most expensive but professional grade for sure. Then you can buy other attachments like monometer,...

I put a stat on already, I think when I go back I'll put a 75va back in, and change wire, contactor, and fan relay. that's gotta do it!

first time 24v side, second time common side. that's another thing throwin me, I cant recall ever havin a common side of a xfmer bad usually 24v side

I got a carrier A/h keeps blowing transformers about one a month, older unit not my install, first time called noticed several old transformers sitting on a shelf next to furnace thought hum that's...

transformer was blown no voltage so still doesnt explain the voltage, was my first thought also

that wasnt the case or I woudnt be on here asking, all wiring was in tact

dont see that as a possibility,theres no low voltage wiring involved in a cap

Just wondered if any body has seen this before. First for me. h/p-a/h r22 30kw heat. all were burnt up: capacitor, contactor, o/d stat, defrost board, thermostat, fan relay, transformer,

call was...

If so couldn't that be bad if sent into the ref system??

I guess that could be possible cause I always shut my guages then the pump then the pump valve. I don't know if I had oil at the guages, I seen it on the Micron guages port and the vac port

I had oil in my hoses the other day after a good vac on a new coil and Ac flushed lineset. It's happened once before but can't recall the circumstances. Just weird I though I have a few theorys but...

yes its one of four must have components. Compressor, metering device, evapoator, condenser

A lot of residential guys are briefly trained and sent out on their own, commercial not so much. So if their not purposely ripping you their just incompitent. Find someone that works for a company...

It's good to get info from people who's not trying to sell you something

This is all you need to do ^^^. These are basic refridgeration issues and should be fixed without having to replace the whole system, these companies kill me these days when it come to fixing your...

bing bing! try this first, its an array of problems it seems, overcharged, restriction, and prob low air on a dirty old furnace fan, check the side of the coil the air goes through, not the side it...

what program or method do you guys use for load calculations? Are commercial calcs easy once manual j is learned

I would try to put it in a closet if possible, attic units can cause you headaches down the road, not to mention service-ability. The second unit would be the smart choice because the upstairs wont...

I have had coils from factory so oily water would drip off of it before it hit the pan, not always but I try to hit a new coil with some foam cleaner helps em drain, as far as the rest stated above...

Man you are a IAQ guru! I'm pretty good at service now so the Air stuff intrest's me and is really technical I think, just another step in this trade i guess

Sounds like it isnt working right at all to me, to have a 10 deg drop acroos your (inside unit) thats bad cooling! They did not install that correctly, by the mod #'s the units should work fine with...

better check that pot relay on that start kit, if it;s stuck closed that start winding is overheating, nott likely it would run a half hour but it could I guess, if your not sure take it off and see...

I'm not the load calc genious on here but I can tell you you go under what the load calc says, so if it said 4.3 you go 4 ton, you could do a two stage also. Shoert cycling is bad and wont remove...

it would have to be pretty close to the motor to do that, cant recall alot being like that, I'm gona look at one and see now!

ya its the aligning part I wondered if there was a better way

you lost me with the stator-atv talk, I think it has other holes so you can tighten the bolts back into to seperate it, it just never seems right

does anyone have a link or data sheet on how to properly remove those pullys with the 3 bolts on the front used on high rpm fans and motors? I know how to get em off but its not the right way and it...

when does the pickle fork come into play??? interesting

better call your installer, has it done this since day 1? might have a plugged drain which would mean all the humidity in your house is going back into your house and in your unit

I dont like changes, I cant figure out how to go to subscribed post?? Used to be the usercp link now IDK>>>??????

ya sounds like your micron guage could be wrong or dirty, clean it with alcohol. can you just vacuum down the guages to see if it will pull down, I use a seperate micron guage so I can just shut off...

more air more amps, could be on wrong speed but probthe half of cat he pulld of the wheel gave you more air more amps. 8 amps is on the higher side not off the charts, try the next lowest speed maybe?

GOOD IDEA:cheers:

well with it being under warranty, thats good at least, verify airflow of course, I'd change txv, dryer, change whatever could even be possibly wrong, your time is too valueble to go back 4-5 times,...

blocked dryer, check temp drop across dryer, txv?? dont sound like it but if I were to open that system dryer, txv, new freon, I bet your good to go clean the coil too! How old is it, sounds like the...

Just have a buddy come by one night and take the outside :payattention:unit, then you csn get a new one

I was thinking the same but mine at home did that 5kw of my heat was on and my house was getting warmer not cooler the heat overpowered the a/c but mine could be different, check ampdraw at furnace...

It's an upflow by the pic

Good thing we have inspectors that don't know crap about hvac to pass that crappy duct job, id start by adding a second return or upsizing the one there now, this should be pretty easy with options...

:ditto: it can't run too long before checking charge on new exp

1 deg says it wasnt your filter dryer, but the txv, and I always do the dryer exp when theres a problem, manf says change dryer when system is opened for any reason but some people just dont wanna...

its not the 14 x 30 grille its the 16" flex goig to it!!! If the duct was 14x30 that would be fine for that, but its not :bump:

that could be, the easyest fix would be to just add a second return somewhere in a common area if possible, but the one near your stat be the primary ( bigger one) alot of things can cause bad...

Alot of times I've noticed the liq line temp doesnt change much the liq press goes up which increases s/c that way, not sure why, but if your not getting s/c adding a ton of 410 will just result in...

Oh and :ditto: to above, we don't know how much air you need but put 14 w damper if I had to guess airflow is like a party the more the merrier lol

Woops didnt mean to quote u :LOL:

Yes you can pull flex over pipe and yes pipe is ALWAYS better than flex, exp if you can access it, run pipe
