article A new study finds that plastic door holders don’t actually work very well.
Instead, they’re just a convenient way to keep the door open.
Researchers at Stanford University and University of Minnesota looked at the impact plastic door handles had on a freezer’s internal temperature.
They found that plastic handles actually slowed the rate at which the freezer would open.
“The plastic handles were the most effective way to speed up opening the freezer door,” said lead author Tuan Nguyen.
“When the freezer is opened, there’s no longer any thermal expansion or expansion of gas and gas is cooled by the heat of the metal handles.”
“These handles are really just like a heating pad that the freezer keeps going through, and the warmer it gets, the more gas the freezer will get.”
As it turns out, plastic handles are actually not the best idea for door opening.
Instead of slowing the opening rate, they actually help the door seal.
A plastic door handle acts as a thermostat, which measures how hot the freezer’s interior is.
If the temperature inside the freezer falls below a certain threshold, the door will open.
This is a good thing.
When a freezer gets too warm, it will start to leak gas and can cause leaks in the freezer.
The warmer the temperature, the higher the leakage rate.
That’s why when you see a freezer leak, the lid is open and you can’t open it.
But a plastic door won’t slow the temperature down by keeping the door from opening.
This results in the door being stuck in the ice and leaking gas.
That doesn’t matter to most people, because it’s not an issue for them.
But to some people, it’s a real problem.
Plastic handles make freezer doors leak, so the only thing they can do is open them.
That means your freezer is leaking.
The researchers wanted to know why.
The reason plastic handles aren’t as effective as thermometers is that they are designed to be easy to clean.
They’re not meant to be expensive.
“Most thermometers are actually designed to go inside the refrigerator,” Nguyen said.
“So if you’re buying a refrigerator that has a door that has thermometers in it, you’re going to have to pay a lot more.”
So they decided to take a look at the cost of the plastic handles.
They analyzed the cost to install the plastic thermometers for the most common kinds of door handles.
It turns out that for the cheapest thermometers, they cost about $20 each.
For the pricier ones, they range from $60 to $130.
“They’re pretty much the cheapest of the thermometers that we could find,” Nguyen explained.
The cheapest plastic thermometer that they found is from J.D. Power, which sells them for $39.
For more expensive thermometers and handles, they found that they were $90 each.
“We really like this price point,” Nguyen told Ars.
The next question is, should you buy them?
The researchers looked at people who have bought the freezer in the past and then compared that to people who haven’t.
“For those people who didn’t buy the freezer, the price they paid for the freezer was pretty much exactly the same as the price of the cheapest plastic door,” Nguyen continued.
For people who did buy the ice cream machine, the prices were even lower.
But for people who had bought the ice creams, the costs were even more expensive.
And for people whose freezer doesn’t have a thermometer, the cost was still higher than the price for the cheap plastic thermistors.
That is, people who bought the refrigerator were paying about $50 more for a plastic freezer door.
“You can get a cheaper thermometer for about $10 on Amazon,” Nguyen added.
“I mean, I would expect that price to be higher than it is.”
The next step is to see if people who are more comfortable with a cheaper plastic door are more likely to be willing to buy it.
That would be an interesting test.
“That would be a test of whether they are more sensitive to price, whether they think that they can tolerate a cheaper door,” he said.
He also wondered if people would be more willing to replace the plastic door if they thought the price was higher than they expected.
“If you were willing to pay $10 more for the plastic freezer, you would be less likely to buy a plastic refrigerator,” he explained.
“But if you were going to spend $30, $40 more, it would be very unlikely that you would have to replace it.”
That is to say, it seems like a reasonable bet that the plastic doors are the least-effective way to open a freezer.
They might not be good for people with arthritis, for example.
So it seems a good bet that replacing the plastic is not the only way to improve the performance of a freezer, even if it’s the cheapest.
