Using Extension Cord with Freezer
Hello,
I just purchased a 7 CFT Magic Chef Freezer from the Home Depot. The place that I want to place it is about 6 feet from the nearest electrical outlet. Reading the manual it states not to use extension cords of any kind. Is the reason they put this on for fear the consumer will try to use a standard electric cord and cause a fire or is it something else? I plan on getting a 15A with a 14 gauge or 12 gauge wire. The line that it is attached to goes to a 15 amp circuit and seeing that it hasn't tripped he line while it is running I should be ok. Any help would be appreciated. Thanks, Nick |

Thanks, Nick Yeah - They're worried you would use a lamp cord type extension cord, or one of those kight-weight orange or green outdoor extension cords that are fine for small leafb;lowers, but not much else. If you gat an extension cord with 14 ga wire, it should be ok, a 12 gauge wire would be better. If it is only 10 feet or so long, it is not any different than if the freezer was on a circuit that was 10 ft feet farther from the circuit breaker or fuse box. Make sure the prongs and the female end of the extension cord are secure, ir, the mating plugs are making good contact to eliinate any overrrrrheating at the plug-in points. Then check it out once in a while to see that things are still fine. Good idea to ask, you are on the right track. Bob Hofmann |

Thanks, Nick My freezer has been on an extension cord for 27 years now. It is, though, a heavy duty one that can handle the load. Use a short cord designed for air condition use and you are OK. They want to avoid people using the wimpy lamp cord. |

snip If this is a permanent location, consider adding a new outlet via surface mounted Wiremold from the old outlet. It will be tidy, neat and safe and meet whatever code requirements exist in your area. Wiremold is quite easy to work with, and total cost will be in the ballpark with a decent extension cord.

Starting the compressor motor is another issue. I'm sure the manufacturer is concend that a low line voltage condition plus a long extension cord could eventually burn the motor. Even though my fridge uses 75 watts, the starting current is 7.5 amps. |

They make a regular 'appliance' extension cord. They are 12ga.

I prefer the metal for power because most of what I do is commercial. The homeowner could put a plastic Wiremold box extension over the existing outlet box and run Romex inside the plastic channel to a surface mount receptacle box and have a neat installation. I wouldn't cable tie the extension cord to nails when one hole straps are readily available, that's silly. [8~{} Uncle Monster |

An electrician told me that the extension cord was the problem. Get rid of the cord (or shorten it considerably to only what I needed) and it will work. I did, and it worked great. Just last week my daughter said that her new freezer was not freezing -- her food was thawed out but still cold enough to cook.

I remembered what the electrician said about my a/c unit, and we moved the freezer to a new outlet. The food was frozen in just a few hours. I have read many articles both pro and con about voltage drops in extension cords. Apparently not everyone agrees with the established theories of electrical engineering. The electrician never did tell me why the extension cord was the problem. All I know is that removing the extension cord caused both the a/c and the freezer to work well. -- You've identified the problem, voltage drop. The conductors have to be sized for the load. An 11,000 BTU AC is a large load. It also has a large initial startup current. That current over a 100 ft 16 gauge extension has considerable voltage drop. If the extension cord was 10 or 12 gauge, it would work, but it's still not advisable. The issue should be much less with a modern fridge or freezer. They typically only pull ~90W or so. Bottom line you want to use a short extension cord that is heavy enough for the load. |

The size of the wire is more important than the length. If you used a 3' cord with 18 gauge wire it would be more of a problem than 100 foot cord with #10 wire. Think of the wire as a pipe. You can only get so much juice through it so bigger is better. |

I replaced my 20 year old one that was using about 250W with a side by side that's bigger, think it's 31 cu ft, the new one uses 90W. The 8.5A that you're looking at may be the max, instantaneous startup current. I've looked at a new freezer too during Sandy with my KillaWatt meter. It pulled ~350 W for a few seconds, then quickly started declining. After a couple mins, it was down to ~100W. |

I think we all agree that extension cords are ok, but they should be made out of wire that is large enough so the voltage drop is very low. The longer the cord, the larger the wire. Wire less than about # 14 should not be used on high current loads at any length. 90W is for a very old fridge. I just looked at the specs of a 33 cu ft side by side and it is 8.5A an 18 cu ft top freezer was 6A No, you have it backwards. Fridges haven't gone up in power, they went way down. I replaced my 20 year old one that was using about 250W with a side by side that's bigger, think it's 31 cu ft, the new one uses 90W. The 8.5A that you're looking at may be the max, instantaneous startup current. I've looked at a new freezer too during Sandy with my KillaWatt meter. It pulled ~350 W for a few seconds, then quickly started declining. After a couple mins, it was down to ~100W. Thinking about it some more, that 8.5A is probably due to the defrost heater that only comes on once a day? That would give you a 1000W heater, which seems reasonable. |
Using Extension Cord with Freezer

wrote in message ... Hello, I just purchased a 7 CFT Magic Chef Freezer from the Home Depot. The place that I want to place it is about 6 feet from the nearest electrical outlet. Reading the manual it states not to use extension cords of any kind. Is the reason they put this on for fear the consumer will try to use a standard electric cord and cause a fire or is it something else? I plan on getting a 15A with a 14 gauge or 12 gauge wire. The line that it is attached to goes to a 15 amp circuit and seeing that it hasn't tripped he line while it is running I should be ok. Any help would be appreciated. Thanks, Nick Keep the cord as short as possible, with conductors equal to or larger than the circuit conductors. Appliance extension cords are made in lengths up to 9' What he said. The big box stores have them. ^_^ [8~{} Uncle Extension Monster |

Thanks, Nick 7 cu ft, what does it pull 100 watts? Likely only 100- 150, Gee maybe 20 ga would work. It's not the running current draw that's of concern, it's LRA or locked rotor amps which is the current the compressor will pull when the system pressure is not equalized and the compressor can't start. If the power blinks or you flipped a breaker on and off for the freezer circuit, you'll hear a hum and a click coming from the freezer which is the high temperature and overload switch inside the compressor snapping off. Many overload switches are inside the terminal cover of small compressors and can be replaced if the contacts erode away. The overload may click several times before the compressor will restart. The LRA for a typical large chest freezer can be 12 amps or more. The electrical specifications for voltage, RLA (run load amps) and LRA (locked rotor amps) are on a sticker that has the model number printed on it which is located inside or outside of the freezer. ^_^ [8~{} Uncle Frozen Monster |
