SOURCE: My Lennox HS22 series split system scroll compressor overheats

There couild be a small blockage in the refrigerant piping. This obstruction could be cyling through the system and causing the pressures to increase and decrease which is overheating the compressor. Normally when the compressor is overheating there is not enough refrigerant getting returned to the compressore to keep it cool while running. When it shuts down the the refrigerant equalizes which can return the blockage back to the coil or just simply dislodge it frome where it is hung up. When the compressor returns to its running temp, it turns back on and can cycle that blockage through the refrigerant piping which sometimes it may go thru and sometimes gets hung up and clog the system again. I would have a certified technician come over and hook their manifold to the system which can easily tell them if there is a blockage or he can trace the problem. Do you know what type of metering device is in the coil inside?

Testimonial: "Thanks Terry I did refrigeration for over ten years but got out of it 15 years ago...It took a while for my brain cells to click.I didn't think about the blockage which still may be a possibility. My pressures were a little low for my ambient temp so I added some freon now I have a good sweat back to the compressor and it has been working good for the last 3 hrs...the temps outside are supposed to hit the hi 90's and I will keep an eye on my head is a split system and I'm getting some sweating at my txv..that is were the restriction usually happens.I used to get a lot of cap tube restrictions in small systems.thanks for the help."

1?Check whether the resistance of sensor is normal,
otherwise replace it.
2?Check whether the sensor wire is short circuit or open
circuit, and whether the plug is well contacted, whether
there is welding off or rosin joint on the electric control
board, repair it if there is any above.
3?When the 1 and 2 are both normal, then the components
or integrated circuit is damaged, the electric control
board should be replaced.

If the unit displays Error E4

1)Check whether the winding resistance and
operation current of the compressor are normal.
2)Check whether the high and low pressure is normal
when the unit is running.
3)Check (whether the coil pipe sensor is normal)
whether the contact of the inserted on the circuit
board is well, the coil pipe temperature sensor is
fixed, the evaporation of the indoor unit is well,
the key is to check the evaporator temperature
detected by the coil pipe temperature sensor has
reached the cooling or heating temperature.
4)Check whether the surface of the condenser is too
dirty, it should be cleaned when it is too dirty.
5)Check whether the capacitance of the outdoor motor
and the fan is damaged, it should be replaced when
it is damaged.
6)If the above items are normal, the electric control
board should be replaced.

Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thank you for using fixya have a nice day:-)

I have a waves airconditioner. Its not cooling well n after some time show e4 error. How to remove the error? Plz help.

This was googled: waves error codes
It showed a page in "images". Stated
"System abnormity" I think. Page was blurry.
Call a tech! Mini splits can be a troubleshooting nightmare! I think its a Fujitsu unit. It would help, and may save you some $$, to call around to find a technician who has worked on mini splits. And maybe find them a 1-800 # that is their tech support # before hand, so if the tech needs it, you have it. E4 is a vague description for a fault. Make sure you have cleaned air filters, cleaned o.d.coil (turn off power at breaker 1st). Changed batteries in remote. Work safe!

We were getting an E4 but now we get an E2 but

I do know that the owners manual should show you what each and every code means? Some times the manufacture will paste a strip located on the panel of the indoor unit showing what each code means. If not, I would contact the factory on this. I know on Bryant, Mitsubishi splits, Day and night, (Bryants), Tranes, Lennox and most all others, do show in the manual and on the unit behind the panel. Try looking for them there.
