Sounds like a wiring or compressor problem. With the unit unplugged carefully look for burnt wiring. That's the best answer I can give without any information.

Check the start relay. If it is OK the compressor is bad.

SOURCE: Everything works fine, except when the compressor kicks in the panel breaker trips.

Most likely a short in the compressor electrical components (relay, overload,capacitor) Supco makes a 3 in 1 that you could use. If this works fine, if not "bad compressor".

Hi,

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong. If you are hearing a clicking or buzzing then check out the last two tips.

Not cooling


is the freezer plugged into a gfi outlet? outlet may have tripped.
if there is power to the unit: (light on, fan running, etc.)
a large clump of frost around the lines/ top shelf, means it could be a leaker and will need to be replaced.
a clicking, humming noise repeating every few minutes could be a compressor start relay.
if the freezer has tripped the breaker, the compressor has developed an internal short and again would have to be replaced

Freezer begun tripping our 20 amp breaker for some reason


ok hi there i viewed the specs for this freezer
http://www.truemfg.com/catalog/servlet/com.apsiva.servlet.HomeServlet
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

Tripping breaker


Hi, this is not a good sign when a unit trips a breaker. I can tell you whats causing this without having you check every thing on the unit. The compressor has gone out and drawing what we call locked rotor amps. This is what happens when one fails, it is the only part on the unit to draw enough amperage to trip a breaker. To confirm this, you can pull the unit away from the wall and unplug it. Remove the lower panel that will expose the condenser fan motor and coil, and the problem compressor. On the side of the compressor where the wires go into it, you will see a metal strap that is hooked around a black terminal cover. Remove it by using a screw driver lifting one end off. Now the cap will pull straight off. You will see a small round overload relay there and it just sets there with a metal clip that holds it on. Remove it also and it will have a blk wire attached to a compressor terminal, that is marked C for common. You will have 2 more for the other terminals, R for run, and S for start. Just pull them off. Tape the ends of the wires up so they don't touch anything and don't worry where they go as this compressor will be done. After you have done this, Plug it in and set the control to cool. Everything now should work as far as light and fans, and the breaker will not trip with the faulty compressor out of the circuit. It would be much cheaper to buy a new or good used unit then to replace this compressor. This has to be done by an expert on this kind of unit. It was probably shorted to ground a internal burn out. Sorry to give this news to you, but this happens. Keep me posted on what you have done.
Sincerely,
Shastalaker7

Actually, its a True T-72 refrigerator. After running for a few weeks, the unit trips the breaker and continues to do it unless I leave it off for a few days and then re-plug it in, at which point it runs...


some manufacturers use a heater in a pan for the condensate water that is generated from the defrost cycle. It is usually located near the evap and compressor area. I've even seen them under the condenser coil. Look for a heated pan. You may have a bad heater. When it goes into defrost, water enters the pan and trips the breaker as the heater may be open and water enters it shorting it to ground. Waiting a few day allows the water to evaporate out. And the process starts all over again.

I would look for this first. If this does not pan out, let me know and we can dig alittle deeper. But try to have more details.

Condensing unit terns off but won't come back on kicks off breaker


If it runs, turns off, then tries to restart and kicks breaker, look for bad start components. Check start relay, start capacitor. It may be trying to restart too quickly and the compressor over amps and breaker trips. The system needs to have at least 3 minutes of off time before trying to restart. This allows the pressures in the system to balance enough so the compressor can overcome the high side pressure and start. I've seen where people turn the control up and down very quickly causing the compressor to over amp and trip breakers and over loads.
Hope this gets it for you.

Kenmore upright freezer model 29238 keeps tripping switch


If the compressor actually runs for more than a second or two its likely the compressor is bad. Some models had a 5 year warranty and some ten years on the compressor only. The replacement of the compressor is likely beyond your abilities unless you are a service technician.

A typical cost for such a repair can be more than the freezer may have cost you if nothing is under warranty. Good Luck.

Once in awhile, Circuit Breaker Trips


Your compressor start relay contacts may be getting loose or worn, resulting in a delayed start on the compressor.
If the start device includes a capacitor, it could be getting weak.
GFCI are not good receptacles for devices with high starting torque.
