Turbo Air Freezers - Page 3 - Recent Questions, Troubleshooting & Support

Tried to find the code "CO" in service manual but to no avail and please furnish the proper model number as none you list appeal. You stated that the unit sat for 5 months so I am wondering if your unit has developed a restriction in the capillary tube as this unit uses R 134A which has this problem.

Hi Tim, I really don't believe you need a charge unless you have had to charge it in the past, because of a leak. What you want to do, find the compressor on this unit, below in back or front, or some are on top. Make sure you feel it running, and see if the condenser fan motor by the compressor is also running. Check the condenser coil and make sure its clean, and make sure the indoor evaporator fan is running. These are things you can check on your own to find out if something is going on with a part. The only time a unit needs freon is if it has had a leak in the passed, and it was never repaired, so it lost its charge when it was shut down for sometime. Check these things and get back to me. We can figure this out.

go to this web site and it will show you where the places you can purchase parts.
Are you sure it's the control and not just a temp probe not reading correctly. If it reads a false number, the unit will either never shut off or never come on as the controller is controling based on incorrect information. You may want to look into that first. Control panels are not cheap.

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.

Change the temp control,check to see if it is iced up on the evaporator

It sounds like you may be low on refrigerant (freon). One way for a novice to check this is to look at your compressor. There are two line coming out of the compressor. The comressor is the black thing about the size of a bowling ball under your freezer behind the grill. The small line coming from the compressor to the "radiator" behind that lower grill should be very hot coming from the compressor. The big line going into the compressor should be very cold to the touch. If that is not the case you are low on refrigerant. Without gauges and a supply of refrigerant you can't fix it yourself. Second thing to check is the thermostat is it set all the way to cold? If not turn it clock wise 1/5 turn and watch to see if the temperature goes down.

This is normal. All commercfial freezers must defrost 3 to 5 times a day, or they will freeze over at the coil and then stop freezing. A timer in your freezer turns off the compressor and turns a heating element on for 10 to 15 minutes. During that time the coil heats and melts frost from the coil. Usually within 30 minutes the temperature will briefly rise to 20 t0 25 degrees F and then quickly drop down to 0 degrees F. The food rarely defrosts in this short period of time..

The thermostat is faulty.

Check the consenser and see if it is clean.
Be sure the compressor is running and not just the condenser fan.

When the temp gets back down to running temp the vacuum will return if the gaskets are properly installed. If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

things that need checking:
refrigerant level. Super heat. Condenser clean? Compressor effeciency.
These are things that an experienced tech can check. If you have some experience and gages/ tools, I can give you some things to do but most of this requires experience.
Let me know if I can be of any further help.

it is automatic. If it is not going into the defrost mode, the defrost timer may not be working.

make sure the compressor is running if not change over load and relay

get a sheppards hook a parts store can help you tell them your prob

go to this site and check out the service manual. I guessed at the unit you had as you did not include the model number.
You can also go to turboairinc.com and search for more info if you need to.

Hope this gets you your answer.

This sounds to me to be a typical "reset" problem, this unit, is NOT resetting itself, after the Temp, is reached, it is meant to restart, and cycle, when the preset limit, is met, but, in your instance it is not, resetting itself, but is "Hanging Up" so either the Thermostat isn't sending a reset pulse, the CPU isn't receiving one, the watchdog timer, doesn't seem to work either, or the CPU, is simply hanging up, on that instruction, this further points to a controller board, being faulty. But as always check, thermostat, sensor, wiring, power, rest the unit.

This is the web site for your manual for your unit. I've had some situations where some rubber type insulation has melted but I've not experienced any problem other than it makes a mess. Hope this helps.
