Blows a fuse when i plug it in - Turbo Air 49 cu. ft. / 1388 liter Commercial Freezer MSF-49NM

The best thing to do is to Google
make model spare parts,
or
make model parts schematics.

If it was a fuse, it would blow and not run again. They do have a device called a 'clixon' that senses overheating. It could also be a faulty Run Capacitor. There is a relay for the compressor according to this.

A. Is it plugged in?
B. Did you turn the Controls INSIDE the Freezer to the ON Position or to a lower setting?
C. Does the Light go on?
D. There is a Fuse that will blow (BUSS FUSE), you will need to change it if when you test it, there is power BEFORE and not after...

If it is a chest freezer, almost certainly it is the compressor. Only way to check is to pull the power plug out then remove the compressor wires from the terminals then make sure it doesent touch the frame of the freezer, then plug the power back in and see if the power trips again. If not, there is the problem.

Your fuse range is too small, change it with a bit higher range.

First check for bunrt wires that can be grounded, then you can disconnect the compressor and plug the freezer and if doesn't blow the breaker , the compressor is bad ,if still blows them ,put the compressor back and try the fan , then try the other fan(inside one) or also could be the light switch, or the defrost heaters.

Hi lewis,

This is very suspect if it blew straight away I would suspect the compressor going to earth, I am still not convinced with the comp after all ts ten year life is up, It could be something to do with the thermal overload on the comp if it has one.
The compressor does run for 12 hours but in that twelve hours does it reach temp? does it actually switch off on its normal routine?
where about in the uk are you?

their is a short caused by the water hose or to much water causing short get a pro be safe.. Tom

did you just get the freezer or move it recently? this unit doesnt have any fans so I'm thinking the compressor is somehow out of place and when you plug it in the compressor is hitting its steel shell from the inside. remove the compartment cover on the side then plug the freezer in and see if the compressor is making the noise..

This may sound too simple. A fuse is a safety. It usually blows when the amps are higher than the fuse rating. Since yours blows immediately, I would look very closly for a pinched wire, a crossed wire, or a wire that has rubbed through. Once that is eliminated, start isolating components one at a time. Check their web site. It's pretty good. Also, their tech support line is pretty good. It's worth the wait. 1-800-233-1940.

good place to start is the starting device for the compressor.slip the cover off the compressor electrics on lhs of compressor usually and you may find the relay burnt out.tyhis is the mostly area but if elsewhere, look at the defrost element and check wiring loom
