Found indoor unit running and calling for cooling,outdoor unit was off and came on while hooking up to low side,low side pressure was at 0-1psi.liquid line leaving was frosted up.shut off outdoor unit and low side rose to about 200psi.clamped on to compressor and started outdoor unit.low side came down slowly as compressor amps rose slowly until compressor went off on thermal.code off of pc inverter board bilnks an overcurrent condition.

Hello Sounds like a restriction/clog if the unit is (pumping down) .try adding freon when the compressor cools off & starts again.See if the low side #s improve.Make sure the service valves are open.

How to troubleshoot thermostat wiring?


I'm not sure if the thermostat is wired correctly. First, the thermostat is wired directly to the outdoor unit (compressor/condenser unit). It is NOT directly connected to the indoor unit. It connects to a low voltage control panel in the outdoor unit that sends a signal to your indoor fan/evaporator. This wire is called the fan relay switch and physically runs between the low voltage controls of the indoor and outdoor units. If the fan relay is bad it's possible that the unit runs continuously. To prevent destroying your outdoor unit there is a safety feature that prevents the indoor fan from shutting down while the outdoor unit is running. If the indoor fan did shut down while the outdoor unit was running than you would slug your compressor. That is, your compressor normally sees refrigerant gas but is instead seeing refrigerant liquid. That would not be good since this scenario would destroy your compressor. It sounds like a faulty fan relay. The actual contactor portion of the relay is in the outdoor unit.

Indoor unit powers up indoor fan runs, has call for cooling outdoor unit will not run, has coms issue


Good. When it calls for cooling the wire conncets to a contactor in the outdoor.
Unscres the center of contactor and then check the contactor by pressing thr' ur screw driver maually. Just only for 5 seconds.
If it works, the contactor coil is defective.replace contactor

My wall split a/c 24000 btu work about 1 hours or more after no cooling and u can see frost in the indoor coil and on the coppers on out door unit and i have low pressure 40


Low pressure and frost on your indoor coil with the copper pipe to your outdoor unit is almost guaranteed a low refrigerant charge. It can also be a bad metering device. You will need to check you high and low side pressures to be sure and make sure you let the frost thaw before checking pressures.

Charging an air conditioning system


R22 systems should run a 68# to 70# suction pressue. If you look at the suction guage at 68# that is a 40 deg evaporator coil temp.

1. what are reasons why refrigerant compressor burn-out? 2. ice build up on suction line. 3. Insuffecient cooling. 4.Outdoor unit not running, but indoor is operational.


On the split system 1. Can burnout from defect, lightening, etc .. 2. Only way ice will buildup back to outside unit is LOW LOAD.. either from dirty filter, dirty coil or fan blades caked up with dirt. 3.. Poor airflow will cause the poor cooling $ Outdoor unit most likely has a low pressure switch causing the outside unit to shutoff until pressure rises.. Has this helped ?

Indoor unit temperature between 60F & 70F after R22 charge..


The pressure changes with temperature, it is not a true gauge to ensure a proper charge.

You should have a 15 to 20 degree temp drop across the evap coil. (return air vs supply air)

Can you verify that the compressor is running?
Not the condenser, but the compressor located inside the condenser (outdoor unit)

it really sounds like it is still undercharged.
Check the temp drop, let me know what it is.
Also tell me what the outdoor ambient temp is.

( for example.... 98 degree outdoors with 85 degree indoor temp could result in pressures something like 325 on the high side and 75 or 80 on the low side.
With the exact same unit, but 80 degree outdoor temp combined with 70 degree indoor temp, your pressures could read 215 low side and 55 low side. Not to mention that more efficient units often have higher pressures on the low side because they have more coil space and remove heat more efficiently)

Blown Transformer heat pump


blown transformers are usually from a low voltage short the first thing i would do is wire a automotive or resetable 3amp fuse in line with the transformer so you dont blow transformer after transformer the wire coming off the transformer that say 24v take that wire a couple of inches down and cut it and install the fuse in series there
24v----------------
24v----------x----------
24v--------{3ampfuse}----------

now you can go through your low voltage wires one by one and test them unhook all the wires to your outdoor condenser at your indoor unit(furnace or airhandler) and try turning it to cool now if you blow the fuse the short is between the tstat and the indoor unit if the fuse is still good leave it on cool and hook up one wire at a time to your outdoor unit starting with R a lot of times your contactor or your defrost board will short out on you also look for pinches in wires wires with cracks in the insulation and wires touching metal this situation can be a real pain sometimes i would recommend calling a hvac company if you start to get stumped
hope this will help you

Outdoor unit will not run


Some air conditioners have a thermostat that will not allow the compressor to run below a certain out side tempature as it will cause liquit to come back into the compressor(called slugging) and damage or destroy it.

Compressor will not start.


Usually short cycling means that High side pressure is getting to high (due to not working condenser fan, or dirty condenser coil), or low side pressure is getting too low (might have low level of freon or restriction in sealed system). low side would drop dramatically if indoor blower is not running, so if air is not circulating thru evaporator coil, coil will freeze up and low side would be much lower then normal. Here is video how I found issue with package AC not coming on. Thermostat call for cool, but condenser would not come on, indoor blower runs ok.

Regarding gas pressure


ok lets see how i can help you. If the units low on gas, suspect a refrigerant leak!! 2nd, what refrigerant it's using? I can't tell you operating pressures if you don't know the refrigerant. (usually the label on the indoor unit right side says refrigerant charge and type.) 3rd desired temperature for cooling is about 68-72 F that's about 20-22 Celsius.

id keep it on 21 C
