Sanyo split high pressure side tube icing

We recommend you get it serviced regularly by an air conditioning company.

You need to spray anti bacterial spray and change the filters to service your air con.

there is no suction at all when the machine is off as the gas equalizes around the system
all you will read is the pressure of the gas in the system and that will tell you nothing
to read gas pressures you need to know the type of gas in the system , have gauges that can handle the high pressures and have two on a manifold so that you can read suction and high side pressure differences
That way you can see if the system is low on gas or over charged

This happens when the drain pipe is too high, or kinked. The pipe must be lower then the drain pan in order for the water to drain. This is a common problem.

There are reasons for.
1. Dusty indoor coil and blower wheel - Clean it.
2. Less speed of blower motor- Replace capacitor/motor
3. Short of gas- Find leak and rectify.

Thanks.

It may be low on freon. Ice on the tube is an indicator of low freon level.

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)

sound to be in heat modenow. If you are after the cool mode, then if you have a cool setting and a heat temp setting, Lower the heat to almost off and set the cool setting to 74 degrees. See if the outside coils get warm. Make sure you are off manualo and n auto. If it runs, give it some time and the tenp of the outside coil will rise and the inside will get cold. Food Luck

u r compressor is not functioning,sure u need the service technician

I work on and like the sanyos.Yes there is usually a crankcase heater and fan cycling controls.As far as efficiencies.....thats up to what you wanna spend upfront or on electricity later on.Im in Ohio.

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.
