Hair Dryer for Defrost

I have always heard that you should not use a hair dryer to defrost the freezer, but what actually happens if you do? If you are careful not to use too much heat in one spot, what is the harm?

No harm in using a hair dryer.

What we do is turn off the refer, empty the freezer and then put a sauce pan full of boiling water on the shelf and then shut the door and wait.

Ice will melt and become loose then you can pick out the big chunks, use a towel to dry the compartment and reload the freezer and turn on the refer.

I've done that for many years...in my RV 's (fulltimer 6 years), and my various stick houses. Just keep the heat moving and it'll melt the ice lickity-split!

as long as you do not melt the plastic parts there should be no problem I defrosted lots of sticks and brick refers the best way is with a small steam cleaner but hair drier is a close second

If the RV maker or refrigerator maker recommended this procedure some genius would turn the dryer on high and mount it steady in one position while they watched some reality show on TV. Then they'd sue everyone in sight because all the plastic melted and their fridge is ruined.

If you have any common sense at all and a 3-digit IQ, a heat source carefully applied is a fine tool to assist in the defrost.

Don't forget the drain cup on the backside of your refer "if" you have one.
My Norcold has a small cup on te backside that the water drains into. I will pull the drain hole thru the back panel.

I agree with most everything that has been quoted above. I have been using a hair dryer for almost 10 years, and nary an issue. I just thought maybe there really was some technical reason not to use a hair dryer other than the obvious risk of melting plastic. I remember seeing someplace, that it could cause an issue with the thermal bond to the cooling unit, and I wanted to see if anyone else had heard the same. I am only assuming here (yes I know what happens when you assume), but I guess before there ever would become an issue with the thermal bond, the life of the cooling unit will probably expire.

I don't use a hair dryer but my wife does and has been using one on RV and home refrigerators for as long as I can remember. I don't think it ever damaged a refrigerator/freezer.

I always use a hair dryer combined with a little common sense (keep it slowly moving and about one foot away from surface). Works well and quickly for me.

The potential harm is you can cause the foam insulation to expand if you heat too much in one spot. You will end up with a bulge in the inside wall of the freezer. IMO, the risk is small if you keep the air flow moving around. Don't allow much of the hot air to hit anywhere there is no ice.

I used a hair dryer every couple of months for about 5 years of full-timing with no problems before we replaced the Norcold with a frost-free residential.

I've been using a hair dryer in both my S&B home & RV for years. Same as previously stated by other members, keep it moving so you don't create a hot spot. You'll be fine.

How is it one careless match can start a forest fire but it takes a whole box to start a campfire?

Me too. Be careful not to have it get in the way when the upper portion starts to drip.

I turn the unit off, empty the freezer and place a small fan inside on the door landing. It takes about twenty minutes to melt any ice. I dry the water, close the door and turn the unit back on. After about an hour, i put the still frozen food back in. Simple.
