DEFROST PROBLEM
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(disconnect the two wires plugged into it and twist them together) 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.
Part 648 is your defrost control. http://www.searspartsdirect.com/partsdirect/part-model/Hotpoint-Parts/Refrigerator-Parts/Model-HTS16HBMFRWW/1811/0166000/G0211146/00003?blt=06&prst=&shdMod=
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.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. It has to circulate thru the firdge. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

Sounds like you have a clogged drain the water freezes melts during defrost. You have to take the freezer floor out. to clean the drain.

Hi,
I think you may have compressor issues...
As the weather is getting warmer for many people their freezer2_bing.gif and/or refrigerator do not work right because of a dirty condenser coil...

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Hi,

This a problem of your timer. There is timer in your Refrigerator which controls the reset(ON/OFF). It seems the timer is stuck/damaged
.
This link is a reference to troubleshoot/repair Refrigerator timer.
Please try those steps.
Another link is here.

If the problem still persists you need replace the timer.

Thanks

either the contactor on the compressor isnt engaging or unit is low on refrigerant(when compressor starts you should hear a snap,or click sound) that is the contactor on the compressor

It sounds like the circulating fan is wearing out. The fan circulates air thru the freezer as well as the refrigerator. When it starts to wear out the force is reduce to a point that the freezer will get cold but the refrigerator will not get cool.The minimum cost of the assemble is around $300.00

It could be the defrost timer the defrost heater or the defrost termostat You can check the heaters for continuity or when the freezer is all cover with ice turn the timer (located in the cold control box inside the refrigerator ) untill the compresor stops and if the heaters start glowing the timer is bad.

Hi: It is either the defrost heater (most likely) or the defrost timer. The airway to the fresh food is clogged with frost. I doubt your freezer is packed as you could put your hand on the vent. If you block the vents this can cause the problem also. Check the defrost heater and replace if necessary. It is a wire coil in a glass tube. if the coil is broken it is bad. Look at your parts list or on line at Sears Parts. to find out where it is. I hope this helps, Jeff

you have defrost problem

Hotpoint Â... | Answered on Apr 06, 2009


If the freezer is working properly, and the fridge is not, it is usually the evaporator fan. It should be located behind the back panel in the freezer. Usually, a fan blade is stuck, or the motor is stuck on it's bearing. You may need to reposition the fan or apply some oil to the bearing. If you cannot get the fan to spin, you might need a new fan motor. Check the voltage first before buying a new motor. You should get around 110V AC .
