Model # t49f 2 dr. freezer unit tripping 20amp breaker at start up. start up components check out good . compressor pressure at 120 stabilized at start up compressor will run approzimately 15-17 seconds pump down to 25 psig and then cut out circuit breaker. i did not have an electrical breakdown on this model, but need a copy,
SOURCE: What do you do to convert a T49F freezer to run as a refrigerator and is this feasible?
First of all the unit uses a low temperature compressor which is designed to work on a freezer. Refrigerators use a medium temperature compressor. So most likely it would be over sized for what you are trying to accomplish,
Secondly the evaporator feed device is designed for "low temperature", not "medium temperature", so it would involve resizing the feed device.
SOURCE: We have a true T49F freezer and the evaporator
Freezers have a sensor that is referred to as a "Fan Delay/Defrost Terminator". It senses the temp during the defrost cycle. Usually, when the evap temp reaches about 50 degrees, there should not be any frost or ice on it. This device terminates the defrost cycle. It also keeps the fans off so warm air is not circulated. When the evap gets to about 20 degress or so, the sensor switches on the evap fans. If the fans are not coming on, either the sensor is bad or the evap is not reaching the proper temp to cause the sensor to turn on the fans.
Hope is helps to clear up some things and point you in a direction as to what might be going on.
SOURCE: True Freezer- The 5 amp circuit breaker trips when the light on
I believe that breaker is actually for door frame heaters. Most true freezers have a resettable breaker for the door perimeter heaters only.
SOURCE: Freezer begun tripping our 20 amp breaker for some reason
ok hi there i viewed the specs for this freezer

this unit must be plugged into a 120v outlet with a 15amp circuit breaker dedicated (nothing else should on this circuit) so all by itself. you have to check the voltage outlet where you plug in. you must have at least 115v or better (125v the most) if you have less then 115v it will cause damage. ok you went and checked all this out and everything is 15amp with 115v or better and it still trips breaker.
ok the running amps is 6.8 amps so to blow the circuit you need 15 amp which is too high.
i suggest you call a refrigeration guy because he will be able to determine if the problem is the compressor (which has a 4 year warranty with truemfg.com only in the USA) or something else. Usually but not 100% what would make a freezer like yours to blow the fuse is the compressor. if it overheats it will do this, if there is a sudden high pressure within the system it will do it, if you have a condenser fan that is not running at proper speed it will do this...
the problem cannot be pin pointed understand please... you have to babysit it, watch for changes in the refrigeration system and the running compressor amps, voltage drops ( this will cause high amps) etc...
Refrigeration is not easy and alot of tech stay away... so those who stick it out make money cause you have 2 choices: buy another one and pay big bucks to get it fixed. at least see if you can find someone to come over (for like $40 - $60) and tell you exactly whats wrong with it... whew... hope this was helpful and not confusing...sorry
