Hi, I have a Turboair Problem with the Turbo Air
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.
Freezer is warm, not freezing at all, fans run
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.
I wondered how long the defrost cycle was supposed
If it's frosted up, it's best to defrost manually with heat gun. Find the timer and advance until it goes back into defrost. The timer looks like a residential fridge. It cut the compressor off and the heaters on.
Please rate solution
Msf-49nm will not stay below freezing!!
My next question is, you say you have to call a tech to come out. Is he doing something? And if so, what? With the limited info I have at this time, it sounds like there may be a refrigerant problem.
Let me know so we can continue.
Am looking forward to resolving this.
Compressor gos to overlaod
sound like a bad start capacitor,if you have a capactance check on your multimeter,you can find the readings on the side of the cap.I always replace the relay,overload and capacitor at the same time. this usually keeps me from coming back and having to replace another part in a short amount of time. Also check and make sure your condensor coil is clean , let me know if you need more help
