Turbo Air Freezers - Page 4 - Recent Questions, Troubleshooting & Support

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.

Since I do not have the exact model number, here is the site you need to visit to get the manual. Hope this is what you are looking for.

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.

try this site and see if you can determine what you are looking for. You gave no model number.

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

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.

Behind the grille on the bottom is a drain pan. May have a crack in it.

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

Give Rick a call at Restaurant Parts and More. Turbo Air also makes Master-Bilt. Rick can probably get what you need. Just have the model and serial. He's good at this stuff. 1-888-814-1110.

I deal with MasterBilt which is a private lable made by TurboAir.
I have several units but only one does this icing up thing. Look for a bad seal on the door gasket. These really ice up if that does not seal almost perfectly. Look for premature termination of the defrost cycle. Check that the heater is pulling amps. The wiring diagram at "turboairinc.com" is very poor but it shows 2 heaters for the refrigerator. They list a diagram for the freezer but it's not there. I know for sure that there is a heater for the evap but don't know about the drain. I've seen some have it and some don't. there tech support line has much to be desired but it's worth a shot. Also, the bottom hinge on the door fails fairly regularly. This allows the door to drop just enought to disengage the switch at the top of the door and stop the evap fan from running, thus causing a freeze up.
Good Luck . You got your hands full with this one.

There is a good chance, if the defrost timer is mechanical, that you can rotate (nudge) the timer to see if it get's going.

Most commercial refrigeration does not use a defrost thermostat, and a lot of it does not use a heater (they use a hot gas bypass valve and pump hot gas through the evaporator, rather than through the condensor.).

Let me know if you need further help.

It sounds to me very likely that your thermostat isn't functioning properly. change the settings and wait to see if it responds. If the thermostat is working it should shut down the compressor when you increase (rise) the temperature and aversly start it when you drop the temperature. Always let the unit sit for 3 minutes for the pressure inside to equalize before restarting. Good Luck

fridge has timer to adjust for defrosting, but the not working working you to manual defrost the unit to avoid ice formation inside the fridge.

That is known as a puffed capacitor and usually indicates a power supply problem as well. The cap can be changed with a 50/50% chance to work again unless it took out other components.

could be a freon leak check condensor lines were you see the oil if lines have oil on them then it is leaking slowly and you need system work

All question need full 'make model (what it is)', first 3 words. Google make model wiring diagram. Brown or Red is normally power and blue is return. https://www.google.com/search?q=Freezer+with+loose+red+and+blue+cables ..

you do not leave them alone they may have refrigerant flowing through them. look in your owners manual/instructions for more info.

Yes

Question edited for clarity and add CAPS. It seems to be a common occurrence on that model due to bad design. https://www.fixya.com/support/t17110008-norfrost_c6aew_chest_freezer_compressor Norfrost is owned by Ebac. Contact their customer service. https://www.johnogroat-journal.co.uk/news/caithness-freezer-name-lives-on-in-england-170710/ https://www.ebac.com/support/customer-service Another way would be to study the wiring as it is pretty standard. The video may help. https://www.google.com/search?q=freezer+wiring+diagram You may be able to freeze this video to note the wiring, although this only shows the thermostat wiring and is a bit fuzzy. Also an refrigeration appliance technician would know the wiring by heart and take 20 minutes maximum to work it out.
