SOURCE: Falling water hits something hot in freezer and causes sizzle sound
the sizzling noise is water hitting the defrost elememt and this is normal - shows the defrost system is working. if water comes on the floor of the freezer, this may be the drain for the defrost water is blocked. remove the freexer back panel and the drain is in the tray where the defrost water is caught. if it is blocked - usually with ice - clear it with hot water and make sure the water drains freely. takes some patience and maybe several attempts
SOURCE: Glowing Red in Dryer
The element will glow brightly with the door open because there will be no airflow through the dryer. DO NOT operate the dryer this way for long periods or the element will overheat and fail. If the element glows brightly (as seen from the rear of the unit) with the door closed, it may be an indication of restricted airflow in the exhaust system.

That's the defrost heater. The defrost sensor has failed. The freezer has to be taken apart to find the sensor. It is usually round, with a couple of wires going to it.

It may cut off by it's self. Your defrost timer is part 13 on this diagram.

I would turn the timer till the compressor started running again. This should cut the defrost heater off. The timer should stay in defrost mode for only about 20 minutes. The timer may be the problem.
Here's an explanation of the defrost.
The evaporator coil behind the cover on the back
wall inside the freezer will ice up under normal conditions. Every 8 to 10
hours for around 20 minutes the defrost timer (or in most newer models the electronic
adaptive defrost control) will turn the defrost heater on to
melt the built up ice. There is a defrost thermostat which prevents the heater from
overheating the freezer by breaking the heater circuit when the temp reaches
close to 32 degrees F. The entire cooling system shuts off during the defrost
cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to
build up until the air can’t flow over the coil to circulate the cold air
through the freezer and into the fridge. The temperature change in the fridge
is usually noticed first followed by the freezer.
If the defrost thermostat is bad it can prevent the heater from
coming on OR it won’t turn the heater off when it gets too warm. It is clamped
to the evaporator coil at the top to sense the temp. If it appears to be
misshapen it is bad.
With an ohm meter it should show continuity when
cold and none when warm.
You can also bypass the thermostat to see if the
heater comes on then. If it does then you know the thermostat is bad and needs
replaced.
The defrost heater is
located on the evaporator. It is in a tube which is at the bottom and can also
go up the sides of the evaporator. On some types you can see a burnt spot if
it’s bad. With an ohm meter it should show continuity from end to end when
disconnected from the wiring in the freezer. You can also test the wiring for
voltage when it’s in the defrost mode.
If
you have a defrost
timer you
can test it. It can be located under the fridge behind the kick panel on the
front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts
down. The heater should now come on. If it does, replace the timer because that
means the timer is not running. If it
doesn't, check the heater and defrost thermostat. Turn the timer again till
everything starts back up to end the defrost cycle.
If you have an adaptive defrost control instead of a timer,
replace it if the heater and thermostat test good. It is located in the fridge
with the controls in some models and on the back in others.

Hi, yes you bet they do, at least modern day "frost free" firdges do. As the saying goes though, "out of site out of mind". Not to worry, this is the way the fridge keeps from frost/ice building up on the evaporator. It defrost's by way of a heater which does heat to a point to melt the frost, be it only briefly though ( usually 10-20 min. depending on the frost accumulated and the bi-metal thermostat tolerance...the part which insures it shut's off ). Anyway, I hope that re-assure's you this is normal and perfectly fine. If you however, think you want a pro to come and look at it, than that is what you should do. Hope this has addressed your concern or inquiry. Thanks for visiting "fixya" for assitance today, please take a moment to rate the info provided to you, whether helpful etc. Thanks again.
