Does turbo air 4ft freezer have a pressure switch?

Question edited for greater clarity.
Question moved from 'Power Computers' to Freezers.

Disconnect the mains power for 5 minutes to reset the control board. If that doesn't fix it, call for service.

Since there is no mention of the refrigerant, and some models are now using R-290 (propane), it's hard to tell what these pressures represent. My suggestion is to remove the refrigerant and weigh in the exact amount the manufacturer requires. This eliminates alot of guess work and is usually the best place to start.

Hello;

My name is Peter. I am a retired field service refrigeration technician.

You do not know how dangerous this is. You have a high pressure side 160 PSI liquid and a low pressure side 60 PSI vapor.

You can get burned from the liquid or the vapor will burn your lungs.

Only a certified technician such as I can do this.

Is it a fridge or freezer, and what are the symptoms, in detail? Is all working normally, just not switching off? Check condenser clear and clean, and try turning thermostat down to 1 (if mechanical) or up to 40 (if electronic)

Hi, Please set your thermostat a bit warm and observe the compressor. Also check your freezer for leaking.

Do you mean the MSF-23NM and the TSF-23SD? If so, you can find the information for them here:

Basically, the difference between the two is that the MSF-23NM runs on more amps and is a new "maximum" series that Turbo Air came out with.

The product spec sheets at the two links above should be easy to download from our site. If you have any trouble, you can call us at 1(800)319-0690.

there is a kit you can get we call it a sheppards hook got to a parts store and the can help

Call Rick at Restaurant Parts and More in Ohio. Give him the model and serial numbers and he can match what you need. FYI, most Turbo Air freezers are also Masterbilt. Turbo Air does the private lable thing for Master bilt.

Hope this helps.

If the fans your talking about are in the refrigeration section, then the unit is not in defrost. The interior fans shut off during the defrost cycle.
There is a condenser fan motor in the machine section by the compressor. If it fails, the problem you described can occur.
If that fan motor is still, and the compressor is cool to the touch, then no power is getting to the refrigeration section.
Could be a bad thermostat, or the unit has tripped off on the high pressure safety switch. The high pressure switch can be one of 2 styles. Auto reset, which means it will try to restart the compressor when the pressures become normal. The other has a lock out feature that requires it be reset manually. If it goes out on the high pressure switch, once reset, check the condenser fan motor to make sure it is running and/or excessive dirt in the condenser, which must be blown out.
Other causes can be a total loss of refrigerant, or a compressor that won't run.
Short of a broken wire all items listed except for a dirty condensor and reset of the high pressure switch, require a decent knowledge of electrical, Knowledge in the use of a VOM meter and amp-probe, as well as a set of refrigeration gauges.

Check the time setting on the defrost timer. It may not be set to the correct number of minutes for defrost. Compare it with the side that is working properly for the right time of the cycle.
