Compressor shut off for no reason

You need to to determine the superheat and subcooling to check for the proper operation of your system when the compressor is running. I ran into a case just yesterday, the breaker kept tripping. Unit had the same readings as yours. This one had a subcooling of >25 degrees and 0 degrees superheat indicating unit was overcharged. I took an extra 8 pounds of r22 out of the system. During the investigation I also determined the filter/drier was blocking the refrigerant flow causing the technician to overcharge the unit. To check filter/drier performance all you need to do is measure the upstream and downstream temperature. The difference should be less than 2 degrees. This one was 7 degrees indicating it was metering flow. If your compressor stops operating before determining superheat and subcooling, you can get a professional tech to recover and weigh out the refrigerant in your system. You can look on the nameplate data on the side of the outside unit and see the ounces of refrigerant it is charged. If the compressor is operable go ahead and adjust charge by recovering the excess refrigerant into a recovery container for that refrigerant. Normal superheat and subcooling is normally around 10 - 15 degrees.
Hope this helps

Superheat subcooling

the model says that this is a cooler/freezer combination unit. super heat has to be measured on each section separately. As a general rule: Freezers run around 6-8 degrees and coolers are 8-10. I have seen freezers go as low as 4 degrees right before they hit set point temp and shut off.

Hi and welcome to FixYa, I am Kelly

Here is a video that should solve the mystery:

This does a much better job than any text that I could post here but just in case take a look at this Whirlpool Job Aid L-55 for Direct Drive Washers. Page 17 shows how to set the Neutral Drain on the Brake Pawl. Also see pdf page 20.

Between the video and the Manual this should help you.

What is the spark plug gap for the ryobi 320vbr blower

Hi and welcome to FixYa, I am Kelly.
The spark Plug Gap is 0.030. Any original or aftermarket spark plug for this unit is pre-set to 0.030. Unless you dropped the replacement plug it should be fine. All Ryobi engines 2 and 4 cycle have a 0.030 spark plug gap.

I've got a Baumatic Mini4 table top dishwasher: what is err6 and what do I do?

Hi and wlecome to FixYa, I am Kelly.

Your table top dishwasher has an open circuit in the thermostat.


Technical / Advice Telephone. +44 118 933 6933


TEL: 0118 933 6922
FAX: 0118 933 6942

T: +44 (0) 118 9336 900
F: +44 (0) 118 9310 035

I do not have the parts list for this unit. You wil have to contact Baumatic to order parts.
To correct the E6 code you will have to have the thermostat replaced or wiring to the thermostat repaired that is causing the open circuit.

Good evening I refill the freon for a Carrier 14000 BTU and to my surprise when I start it back it was within a couple of minustes full of ICE. What can I do ? Let some gas escape. How do you control the...

you must charge the unit in accrodance with the manufacture recommendations posted on the side of the unit. check your superheat by converting low side pressure into temperature and get the temperature of the low side line and subtract them to get your superheat reading. It must be 10 degrees F for proper operation.

13 degree Delta T

I assume r-22 refrigerant by the pressure... you have a saturate temperature of approximately 41 degree and 71 degrees at the service port this equates to a 30 degree superheat. a condenser saturation temperature of 105 degrees and since the liquid line temp at the service valve is not given only the enterin indoor coil on the liquid line a 96 degree temperature this would equate to a subcooling temperatureof about nine degrees. You have too high of a superheat reading. verify that the bulb for the txv is correctly positioned and insulated. if it is then you need to remove the bulb from the suction line, hold it in your hand to warm it up and see if the superheat changes. you could also have issues with your ductwork. If the supply temperture is around 50-55 degrees then the unit is doing all it can.. Check the txv and the ductwork as the subcooling indicates that the condenser side is doing it's job, but the superheat readings indicate that you are starving the evaporator..
