Most window air conditioners have a little sticker next to the
controls: "Do not turn on until this unit has been off for three
minutes."

Why not? What happens if you turn it off, then on again one minute
later?

It'll suck one of those "Do Not Remove!" tags off your mattress, and

The motors are usually pretty beefy, and draw a lot of starting current. You can
burn them up with rapid repetitive starts.

The air conditioner compressor motor may not be able to start when the "high
side" is near or at operating pressure. When the machine is off, the high
side liquid passes thru a small tube into the "low side". When the "high
side" and "low side" have the same pressure, the compressor can start
without any load.
If you try to start with a load, the machine may still start with a grunt.
If it can't start it will quickly overheat and the motor's internal thermal
protection will trip. The machine will turn off the power to the
compressor motor and will not turn the power on again until the motor has
cooled.

You're supposed to give the AC's refrigerant system a few minutes to equalize.
Y'see, the refrigerant (let's just say "Freon", o-tay?), in a gaseous state, is
compressed by the, uh, compressor. It travels to the condenser (located at the
OUTSIDE end of the AC) where the gas is cooled (subcooled, more like it),
forced thru an itty-bitty capillary tube, and goes on to even more adventures.
But, you didn't ask for the rundown on how the AC *works*, just WHY you should
give it that 3 minutes.And here it is:
In an AC that has been off for more than 3 minutes, the pressure of the Freon
at any one point in the closed refrigeration system is equal to the pressure at
any other point. "Equalized", in other terms. To start up the AC's compressor
at this state of equalization is nice'n'easy on the comp's motor.
However, after the unit has been running awhile, there is the differential in
pressure that I spoke of. If you try to turn the AC "on", the compressor's
motor cannot begin to turn before it draws so much "locked rotor" current
(amps) that your circuit breaker trips. Keep this up, and the compressor will
burn out.
In most AC's, there is a device known as a "thermal overload" that senses the
extra current being drawn by the compressor. The TO, being a bimetal switch,
heats up, and disconnects the compressor from the line. The bimetal cools down
after a few minutes, pops back into place, reconnecting the line. The
compressor tries to turn on, and it either indeed does turn on, or if the
pressures haven't yet equalized, the TO will kick out, only to reset in another
few minutes. You can demonstrate this for yourself by:
a) Run your AC for about 5 minutes
b) Turn the THERMOSTAT control down until you hear the comp stop running (just
the blower fan will be going now)
c) Wait 3 seconds, then turn the THERMOSTAT control up to whatever setting it
was at before.
You will hear the compressor groaning as it tries to overcome the unequal
pressures, then it will stop groaning as the TO kicks out.
After a few minutes, the TO will reset, and the comp will try again.
The TO, which costs the AC manufacturer about 95 cents, isn't designed into
all ACs (I wonder why not?). But a lot of Mfg's mold the words "Wait 3 minutes"
onto the units that actually HAVE a TO. Here it saves the cost of having to
mold the line on some plastic grilles, but not on others.

The motor will stall, and maybe blow a circuit breaker.
When running, it builds up a lot of pressure on the high-pressure side
of the refrigeration system. When restarting right away, the motor
has to start against that pressure. If you wait first, the pressure
equalizes in the system (the hissing you hear after shutting it off).

Is that a problem? Does anyone use kapok any more?
I seem to remember someone on this n.g. saying it grows wild in the

years ago because one tennant flipped the unit from cool to heat while
running. This was one of those units that sits below a window and does
both heating and cooling. It was on cool and running and he flipped it
to heat and it burst into flames. Whole building went up.

which still has high pressure in it and is likely to "stall" when turned
on because it doesn't have the "running inertia" to pump past that pressure.
Waiting a couple of minutes lets the trapped high pressure bleed off
into the evaporator coil through the capillary tube or orifice so the
compressor can start spinning again without stalling.

everybody had a manual transmission car was the ability to "push start"
a car with an almost fully dead battery.
I also miss the days when car bumpers were just that and you could push
start a car using a running car. Or if there was something really wrong
with your car beyond a weak battery your buddy could push your dead car
with his live one and get you home.
Try that nowadays and you're looking at a BIG repair bill for the crappy

Cars these days don't have plastic bumpers, they have metal bumpers with plastic shrouds. And you can push as long as the right parts of the shroud line up.

Old style bumpers probably only worked once for anything more than a kiss,

The car was also very free-rolling. At supermarkets etc, I would push
it up to speed pushing on the driver's doorframe while holding the
steering wheel. Then I would jump in, clutch and shove it into
second, then drive away.
So I solo-started the car probably a few hundred times before giving
up on that car.
