I made video how to replace compressor on true air beer cooler, should be the same for most of prep tables and etc. Hope That helps someone. REPLACING COMPRESSOR TRUE AIR BEER COOLER R134A
You really don't want to do that. Aside from allowing the compressor time to take on the post defrost load, its a safety to keep the freezer door from blowing off due to the rapid expansion of the air it would cause.
When a freezer is not working the door frame heaters don't know and just keep on heating as long as the unit is plugged in. As far as being stuck in defrost, there are safeties built in to keep that from happening. If it truly is the case components and wiring have been changed and really will require a tech to sort it out. Generally though, the door heaters will make it hot inside if the compressor isn't on. You might want to take a closer look and feel the compressor and see if its hot and trying to come on. Hope this helps and good luck.
Hello there: You didn't give out enough informations for me to think what is wrong with a new unit like yours.. What did the serviceman been doing durring these 6 times service call. Did the unit ever work even for one day? Did he change the defrost timer or just made adjustment on the timer. What happen, is the unit icing up so much so that the unit is just a block of ice and that blocked the circulation of the freezing cold air around the unit . Ice is only 32 degree and that is why you only can get 40 degree box. May be the drain tube always frosten up that cause the ice building back up to the coil and form a big lumb of ice. Let me know what is happening , did he add some gas in everytime he service your unit? Let me know more and I will try to solve your problem. Dickson
