Great idea, and no, it’s been warmer than normal, but not high humidity.
I just saw that story yesterday! I can assure everyone that is not an issue I’m having with the freezer!
I’ll try the $1 bill.
Warmer than usual can include more moisture in the air. Not sure how the relative humidity scheme works in great detail. Also the freezer may be doing longer and more cooling cycles than frost thawing cycles if it is very warm. Not sure. But possible.
Use a twenty.
Because inflation.
But, inflation will just make the seal tighter.
Problem solved 
I’m trying to fit the ice cream and blew a seal joke in here, but it’s not quite coming together for me.
I can help:
Q: Why did the walrus go to the Tupperware party?
A: He was looking for a tight seal
[I feel like that should pass muster, no??]
I’ve also heard, among car enthusiasts:
Mechanic: You blew a seal
Customer: First, can you fix it, and second, leave my private life out of this.
[We’re here all week]
Try the veal seal.
This has become too much fun! Use a $20,
and then you all ran with it!
Hey, treat yourself and splurge a little. Use a five.
ETA: Never mind. Sheesh.
The only other reason to panic is if the timer unit has died, and the heating (for frost free) stopped working.
As mentioned, there are heating coils along with the cooling coils. There’s a timer that runs the cycle - run the cooling with fans, to cool the refrigerator (turns on or off when thermostat registers right temp). Every so often, the fans stop (no need to heat the whole unit) and the heater coil melts any frost buildup which drains down into the evaporator pan under the unit.
I’ve had one of my fridges where the timer died, and a same with a friend of mine. The timer used to be mechanical - moving part, easy to die. My friend’s dies on the ehating cycle, turning the fridge into a warming oven. Mine, the fridge simply stopped defrosting. The coils slowly fill up with frost/ice and with the metal fins on the cooling coils burid in ice, the fans can’t blow enough cold to keep the fridge cold and it slowly stops cooling enough.
The only way to tell this problem from one where there’s a loss of refrigeration fluid is to open up and see if the coils are full of ice - or leave the fridge unplugged and open, see if the ice melts and the fridge will work normally for another few weeks (depending on ambient humidity)
Fortunately in the last two decades or so, the mechnical timer has been replaced with an electronic one, a lot less prone to fail.
(A more interesting issue is when gunk (usually flakes of onion skin? Fluffy dust balls?) clog the drain so the water doesn’t drain from the coils when it is melted. This also means a fridge that does not work very well, and often a puddle at the bottom of the fridge and them the floor. A pipe cleaner can usually be used to clean the tube coming out the back of the fridge.)
Good news, it seems to be ok! Maybe I’ll take those bills I was going to use and treat myself , thanks all!
