By interface sensor do you mean the thermostat?
I'll post the links since the files is to big to attached
Some install info about the comfort zone 2
Clapped down TXV possible, might try heating up the bulb to get it to open.
If suction is dropping on start up I wouldn't be looking at the compressor just yet.
This may help if you don't already have
here you go
Its true that on service or install it would be unlikely to see the low % on the compressor since...
3 & 5 ton can reduce down to 40% capacity
2 & 4 ton can reduce down to 50%
Edit: if you are wondering the reason they are grouped like that is 2/3 and 4/5 have the same inverter.
I was just wondering if anyone had the manuals for these.
My 2 cents, saddle tap on the discharge line of the compressor, shouldn't get much of a pressure drop in the cond coil between the discharge and service valves, can also do the same thing on a...
Airflow is a good thing to check, if you get a call back confirm heat rise, gas pressure and if you have an N-coil for the evap that doesn't match the furnace casing size wise make sure its...
Just not pushing enough liquid to the metering device.
Let us know how it goes, low split backwards high/low my moneys on the compressor.
If it was a Heat Pump bad RV could produce the same...
Discharge line temp could be used to check the compressor.
High Side Sat temp should be +20 ambient (15-50 superheat on DL).
Low temp IIRC no heat of compression.
I was just wondering why 3 phase compressors/fans run backwards sometimes?
I know reversing any 2 leads will fix the issue and it always seems too but I was curious as to if there is a...
Just FYI Carrier TXVs are set for 4-12 SH at the Evap.
It is a 5 ton A/C + furnace R410A, just had the ducts sealed so they "should" be good.
Never thought about the electric heat issue, I'll keep that in my toolbox if I see the same issue on a fan...
Yuppers liquid at ambient or below=liquid line restriction was my first thought, I was just excepting higher high side.
Refrigerant cycle dxing is definitely a weak point for me as itís so...
Can't wrap my head around something for some reason today, any ideas.
With good subcooling (14) and superheat (13) and good airflow (350 per ton verified) what could be the cause of a...
In the OPs case wouldn't a voltage drop also have been seen with the old unit if this was the case?
I thought all induction motors had the potential to dim the lights even if everything is sized correctly.
Did the old unit have a start and run cap for the comp?
Somewhat guessing but I think...
nevermind no kit should be needed.
Might want to give your local distributor a call, IIRC it is approved with a kit.
The limit tripping issue happens on all N-coils+furnaces just gotta position the coil correctly so it isn't...
A 24ANA7 Should have a two stage Bristol recip comp in it. (should have a high and low contactor)
High stage failure is related to a VS-VR trip, control board doesn't sense voltage when it should...
How do ya'll feel about changing the compressor oil on a moisture bound system?
Reasonable or just let the drier do its thing?
Coil is R-22 right, a triple evac with nitro purge would have ensured there was no moisture in the system.
How did you come out on this one?
As someone mentioned how the coil sits on the furnace can effect airflow but typically that will show as high temp limit trips.
A blower freeze test...
Just wanted to introduce myself to the forum.
I'm new to the industry been in it a little less then a year. I'm looking to learn everything I can about it and I've learned a lot...
