a/c problem everythings running but need help

[Sicofthis]

Not saying this is it, but I've had two units do similar things with the fan blades in the wrong position on motor shaft. 1/2 an inch or more too low (or high though both of mine were too low) can make a difference. Check airflow with a piece of paper, move it over all fin surfaces, it should stick against coil. Any idea if the motors been changed before? Definitely seems like your having a heat rejection problem.

never been replaced but im wondering if the homeowner bent the blade cleaning out the unit

Anyone!!!!!
I wish I was there.
Sometimes it's hard to troubleshoot over the forum.
I'm sure someone will be here soon.
To straighten out both of us.

I can tell you this much.
If u are checking ur high side on condenser port
And it shows that high
Ur condenser is not doing its job.
The flash gas to ur liquid line is what's causing ur fluctuation.
Not enough condenser,
Not enough air flow,
Go ahead replace the blade
It needs to be replace anyway, since it's bent
It will make bearing on motor go out.

I'll step back and see what others say

I think you could tell if it was bent enough to matter. Did you amp fan motor and compare to nameplate.

I agree if it's bent replace blade. Go ahead and bring a motor with you too.

should the amp draw be half of the rla on one leg I think the rla was 1.2 & .6 on one wire

Ok I have a few questions..

How was the unit performing prior to this year? Cool the house ok? Make set point and shut off? Did you ask the Homeowner these questions?

Are the indoor and outdoor units a match? How old is this unit?

Also when you evacuated the system are you using a micron gauge?

[Brad gall]

ran fine 8 years, pumped down with micron guage. matched amana 2.5 ton

Measured on the line wires amps should be near nameplate rating. Not half.
Did you ever make it back to this job?

[Brad gall]

going over when I get a motor an blade just i ncase. It seems the condenseris not rejecting the heat an the condeser is clean for the amp draw to be that low???
