Nor-Lake KLF7766C Commercial Freezer - Answered Questions & Fixed issues

sounds like a bad defrost terminator or timer wired wrong. won't make temp as the evap is not clear of ice/frost build up. check your wiring diagram for location and operation of terminator.

I would start there. If the thermostat has an off setting, turn it there and see if it goes off. If not, try turning it to it's warmest setting while the box is cold to see if it turns off. To test to see if the relay/ contactor is stuck/bad, kill power to the unit (Unplug or turn off breaker). Disconnect one wire to the thermostat. Restore power. If unit runs, bad relay/contactor. If unit does not run, I'd replace the thermostat. Make sure the sensing bulb of the thermostat is in the conditioned space of the box or in the return air (intake) side of the evap so it can sense the box temp.

start with checking the freon level. If too low, the txv will open and try to feed the evap. this can cause some overfeeding and give you some frost in some cases. It could also be a txv not feeding correctly. usually and overfeeding condition. causes frost build up on line and compressor and pressure in evap too high to remove the heat needed to properly cool. If a cap tube system, usually a sign of over charged or a real dirty condenser. In both cases, an evap fan, not properly working will cause a freeze up of the evap causing a high box temp and frost build up on the line and compressor.

Bad fan delay switch.

Most likely there is a charge issue. A low charge could create the issues you are having.

Also, a faulty or defrost clock could also create issues if the system is freezing up.

L1 goes to 1-2 on Clock, L2 or Neutral to N on Clock, Defrost heater to 3 on Clock, Defrost Limit/Fan Delay to X on clock

I have a generic wiring diagram that I use on all my installs that works very well. It is basically the same for most all commercial walk in freezers. Send me a email address and I'll scan and forward what I have.

either the cold control thermostat is defective or the rtc overload contactor has welded itself together and cant open and close the power contacts to the unit,un plug the cold control and see if the unit stops then

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

Yes

Hey. I dont suppose you figured out where the wires went all all? I've done the same thing ????

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.

Question edited to add maker! All questions need 'make model (what it is) as first three words. That is an overheating fault. Replace the fluff with no fluff. Make sure the condenser coils are free of dust and there is good airflow Or It is low on refrigerant gas and you need a service tech.. ..

Is it on Economy Mode? That only chills the bottom area. Check the condenser fins are cleaned of dust. That needs doing every 6 months. Or it needs refrigerant gas. ..

Question edited for clarity. Question moved from Star Computers. Greetings from Toronto! It is made by Midea and sold to Walmart as a batch, "make us 10,000 at $100 each. We will sell for $280 until they are gone". All the retailers are out of stock including Amazon and Wilson's Home Store. Choose another make and model, bottom of this page. Home Depot, Leon's or The Brick are a good bet for Freezers. https://www.dontwasteyourmoney.com/products/arctic-king-arc070s0arbb-7-cubic-feet-chest-deep-freezer/
