Chemical odor in freezer

Turn off the power to the refrigerator/freezer by flipping the appropriate switch in your breaker panel. Alternatively, unplug the refrigerator from the wall outlet.
2
Open the freezer door. Remove any items from the shelf directly under the light shield, then remove the shelf.
3
Press down on the top, front edge of the light shield until the locking tabs slip out of the slots. Swivel the light shield downward slightly to release it. Pull the shield out of the freezer compartment and set it aside.
4
Turn the light bulb counterclockwise to remove it. Insert the GE replacement bulb into the light socket and twist it clockwise.
5
Reattach the light shield by sliding it into place. Gently push the tabs into the original slots.
6
Insert the shelf into the freezer and reload it with the frozen food removed earlier.
7
Close the freezer door. Restore power to the refrigerator by flipping on the breaker or plugging it into the wall outlet.

Have you tried any other outlets on a different circuit? It might be that there is already close to max load in the circuit and when you plug in the freezer it's enough to trip the circuit.
The next thing it could be is that the breaker is weak and needs to be replaced.

Make sure you have enough amps in the outlet its plugged into. The kitchen outlet might of had more amps than the garage outlet. Also, try unplugging it for a few seconds then plug it back it which might reset it.

The first thing you want to ensure is that power is actually getting into the unit. i suggest that you do that by plugging a night light into the outlet and verify the presence or power. If no power, check your breakers. If power is present note that A chest freezer has only two working parts; the start relay that help the compressor start and a compressor. If you are getting clicking sound, your start relay may be out (inexpensive if you can buy it and install it yourself) or a bad compressor. if you need to call a tech for the repair, you may be able to purchase a new chest freezer that now consume HALF the power and for less than cost of repair.

most refrigerators have a small drainage hole leading from the inside rear of the compartment to an overflow container behind the unit, pull the unit away from the wall and check if the liquid in the container has become stagnant, if so simply clean it out and run a small amount of bleach down the hole to disinfect the tube.
hope this helps.

Does your refrigerator have a water filter? if it has one it will be in the kickplate/grill below the freezer door. If it has one replace the filter.

if its a sweet sickly smell then its possibly just a relay thats burnt out,should be cheap enough to replace,its the call out thats the killer.

All fridge and freezers should be plugged into an NON-GFCI protected outlet, since the inital start of the compressor can cause the GFCI to detect a millivolt surge, when the compressor starts, causing the GFCI to trip.

If this is in a kitchen, you should change out the outlet to a non-GFCI outlet BUT only to a single outlet that only has the freezer plugged into.

If it's in a basement, garage, or some other place with a GFCI outlet, you can change out that one outlet to a standard single outlet device of which ONLY the freezer will be plugged into and remain code compliant. You will need to make sure that any other outlets served by that current GFCI outlet stay protected, by installing the GFCI you swap out, and put it in place of the NEXT outlet in the circuit.

By doing that, you will have the first outlet that was the GFCI, now a single outlet NON-GFCI serving the freezer, but the next outlet in the branch circuit gets a GFCI outlet, thus protecting the rest of the circuit, in compliance with the NEC (National Electric Code)

If you need further help with this, please comment back and I'll check back later and provide you more detailed info. Of course, be sure to turn off the breaker to this circuit before making any changes to the outlets, etc.

Hope you find this Very Helpful and best regards!

i would take the machine outside and blast it with a hose. use hot water mixed with bleach and dish detergent to clean the inside  thoroughly.

IF THERE WAS A LAYER OF ICE ON THE BOTTOM OF THE FREEZER, THE DRAIN IS PROBABLY PLUGGED UP. IT WILL NEED TO BE CLEARED BEFORE PUTTING BACK INTO SERVICE OR IT WILL JUST DRAIN INTO THE FLOOR OF THE FREEZER AGAIN. AS FAR AS THE ODOR, TRY PUTTING CHARCOAL IN IT TO ABSORB THE ODORS. IT WILL HAVE TO BE LEFT IN THERE FOR QUITE A WHILE. WHEN THE FREEZER IS CHILLED, IT WILL LESSEN THE SEVERITY OF THE ODOR. IF THAT IS UNACCEPTABLE, THERE ARE COMMERCIAL ODOR NEUTALIZERS ON THE MARKET YOU CAN USE.
