Six years ago I bought a larger refrigerator/freezer and put the original (with the house) refrigerator/freezer in the garage. I keep it for drinks. Have not had any problems, thus far.:pray::pray::pray:

Most Ref and freezers require a 20 amp
 

Most Ref and freezers require a 20 amp circuit your outlet is probable only a 15 amp and more then likely why your having an issue or you have to much on that circuit . check the breaker to see or get an Electrician to look at it a good handy man can take care of it as well

No problems at all, chest freezer in garage.

2 full upright freezers
 

We have 2 full upright freezers in our garage. I had 2 20-amp outlets added to the garage one dedicated for each freezer. Electrical code is that you do not have to have a GFI outlet for a freezer in the garage if the outlet is dedicated to the freezer. When the electrical contractor installed the outlets he insisted on installing with GFI outlets. I changed the outlets to non-GFI outlets myself. If we ever sell the house, I'll install replace the non-GFI outlets with GFI outlets as the outlets would no longer be dedicated to a freezer.

The recommendation for freezers is that the appliances not be on a GFI circuit as the motors in the freezers starting can occasionally cause the GFI outlet to trip. My recommendation is that you have a dedicated outlet installed for the appliance and have it be a non-GFI outlet.

Have had my chest freezer in garage for 20 years. Sided it with insulation panels. Yes, electric does go out as is somehow connected to lanai and rain knocks it out. After 2nd time got alarm from Amazon. Very loud let’s me know it’s off, so I know to turn it back on after electrical failure.

We have had both a chest freezer and an upright freezer; more importantly, from the outset we had installed a dedicated electrical outlet for their use. Not one problem in 9 years.

I have a cheap ($125) Sam's club chest freezer in my garage for over 2 years. I keep a remote temperature alarm in it. It has never gone above -2 F despite the fact our garage faces due WEST and afternoon temps exceed 90F for 2/3rds of the day and into the evening. At this moment it reads -6F and it is already 84F in the garage at 10:30AM. Only gripe is I have to defrost it every 4-5 months from opening it in the high humidity in the garage. Didn't want to spend the $$$ for a self-defrosting model and an upright wouldn't fit plus this provides more than enough room for our needs. No electrical problems either.

Edit: There is one problem. My wife is just barely 5' tall and she kind of disappears when trying to get to something on the bottom!

Neighbor should look into a a remote WiFi temp monitor. Set it about +10 degrees and you have an early warning. The cheaper ones like this take a while to respond to change of temp (not instant) so set it with enough lead time. They also make them to monitor multiple sensors with different functions.

Have had a garage refrigerator for about 23 years and not one problem

Consider the directional exposure of your garage.We have a spare refrigerator w/ top freezer in our west-facing garage; with the brutal summer heat (even though we have attic fan, insulation out there) that frig works hard and seems to get mildew along the door seal, etc. It works now but who knows for how long (5 years and counting). No problem with circuit breaker.

We have a 6' upright freezer in the garage. No issues at all. However we have a solar attic fan. We also have a garage fan that vents to the attic.

No issue with breakers. Have chest freezer and lg. dorm refrig in garage. We insulated garage doors and crack open window for ventilation.

Have a spare fridge on Lanai(enclosed) but gets very hot in the dead of summer. So far, no problems what so ever. Sister in law has a fridge in her garage and no problems either.
