Not keeping cold or freezing


Either the pumps not running, the gas has leaked or the temp control has failed. You need an appliance tech to check things. You cannot fix the pump or gas yourself.

Defrost timer does not advance after defrost


Hi,

During this time of defrost you manually advanced into, Did the heater turn off them self? If they did the defrost thermostat does work, if the heaters stayed on the entire time (1hr) than the thermostat needs to be replaced as well as the timer. The thermostat is a cut off device to prevent the over heating of the freezer and liner (safety device). Think of a defrost timer as an egg timer, this timer runs regardless of function just advances like a clock. The thermostat turns off the heaters when they reach a temp rather then time. I hope this answered your question, good luck

How to set the defrost duration on a timer


Copy following link for defrost timers:
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

There are 2 general types defrost timers.
Time activated - Time terminated
Time activated - Temperature-pressure terminated, with timed termination back-up

Here is basic image:
http://waterheatertimer.org/images/8145-work-image.jpg
Rotate dial until current time lines up with pointer, insert tripper pin on outside edge of dial to select defrost start-time, move defrost duration tripper on inner dial to set termination time.

Each defrost timer is slightly different:
If timer is time-terminated, then wiring follows certain diagram.
If timer is temperature-pressure terminated, then different wiring diagram is used.

Defroster timer


Hello there,
Defrost timer is what is set automatically by the defrost unit consisting of the defrost thermostat, defrost heater and the defrost timer. It is the timer that sets the routine timing of self defrost in the refrigerator.
If the defrost timer goes bad, it will stop the defrosting cycle of the refrigerator.
HERE ARE SOME TIPS ON HOW TO TEST AND REPLACE YOUR DEFROST TIMER. http://www1.fixya.com/support/r10523722-test_defrost_timer http://www1.fixya.com/support/r10523742-replace_defrost_timer

I have a paragon 8145-20 defrost timer. do you wire the compressor to the timer? I cant seem to find a wiring diagram on how to wire this correctly


Link below has wiring diagrams and wiring manuals for 240V 8145-20
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

I am not expert installing defrost timers.
According to information from Paragon, 8145 is for hot gas defrosting. 8140 series are time initiated, and pressure-or-temperature terminated.
Wiring diagram does not show compressor wired to timer.

The cycle works like this:
Timer is running but defrost is not switched ON.
Fan is ON.
Timer switches ON and activates defrost cycle.
Fan turns OFF. Hot gas valve turns ON for defrosting.
Cycle limit switch is temperature or pressure sensitive.
Cycle limit switch reaches trip point, timer switches OFF.
Hot gas valve turns OFF. Fan turns ON.
So fan is off during defrost cycle.
Hot gas valve turns ON when timer switches ON.
Timer is switched OFF by pressure-or-temperature limit switch.

Frigidaire PLHS269ZDB9 is not getting cold enough to freeze or make ice. I took off the panel , there is an ice block on the thermostat to the evaporator. trying to defrost.


When the refrigerator is running ( cooling mode ) the defrost timer contacts prevents any power from getting to the defrost heater. When the defrost timer turns off the power to the compressor and fan motor(s) the power is then redirected to the defrost system. The defrost timer motor


Defrost thermostat:
During a defrost cycle, the defrost heater causes the metal alloy in the switch to warm and as it does it curls back and breaks the circuit. As the metal cools, it makes a closed circuit again. A defective thermostat can prevent the defrost heater from coming on or allow it to overheat which could result in heat damage or fire.
The defrost thermostat is located near the defrost heater and is wired in series. It is usually located at the back of a side by side freezer, behind the freezer back wall of a top freezer or under the floor. It will be necessary to remove obstructions such as the contents of the freezer, freezer shelves, icemaker and the inside rear or bottom panel of the freezer. At room temperature the defrost thermostat is an open circuit ( no continuity ) and when cooled down the defrost thermostat closes the circuit ( has full continuity ) to allow the defrost heater to come on.



Defrost timers:
The defrost timer is sometimes found behind the front grill of the refrigerator. It may also be found behind a cover plate inside the refrigerator or freezer, in the temperature control console, or behind the refrigerator near the compressor.
The timer is usually held in place with one or more screws. Remove the screws and gently pull the timer out far enough to disconnect the wiring connector.

Locate the timer switch and turn it clockwise until you hear it click. One click and the refrigerator shuts off = defrost mode, second click the compressor and fans come back on = run/cooling mode.

*Some defrost timers are a constant or continuous run timer, which means when ever the refrigerator is plugged in the defrost timer is powered up and running. Some defrost timers are an accumulative run timer, which means when the refrigerator is off the defrost timer is off and not running, when the refrigerator is running the defrost timer is running. This is also sometimes called a demand defrost. The power for the defrost timer goes through the cold control first on an accumulative defrost system. The timers are often the same but will be wired differently to get the different operations.



Defrost heater:

Test the heating element for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should display a reading somewhere between zero and infinity. Because of the number of different elements we cannot tell what your reading should be, but we can be certain of what it shouldn't be. If the reading is zero or infinity the heating element is definitely bad and should be replaced. Proper power ( careful!! ) to the heating element ( 110-120 volts AC ) and the defrost heater does not come on = bad defrost heater.

Some newer refrigerators have been using an electronic board instead of an mechanical defrost timer. The adaptive defrost control does the same job as the defrost timer ( shuts off the refrigerator cooling items and redirects the power to the defrost heater for the defrosting cycle, then redirects the power to the compressor and fans to come back on when the defrost cycle is over ). This adaptive defrost system is a bit different when testing, normally speaking if the defrost heater and defrost thermostat ohm ok, we replace the adaptive defrost board.

MODEL # GSH22JFTAWW won't go into defrost had board changed out and the element and the temp sensor and temp limit sensor how do you put into defrost mode maunally and what is wrong with it have to...


Which temp sensor did you replace? The one that clips to the top of the cooling coils is the defrost sensing thermistor. The other "temp limit sensor" is thermal cutoff switch that opens the defrost circuit should it get to warm. Be sure you got the right part for this! There are a couple of different temperature rated cutoff thermostats out there and this model uses a pretty high temp rating.
As to your question of manually putting it into defrost, you would need to unplug the refrigerator and disconnect the power ******** of the control board (the only jack that mounts parallel to the board and should be a green colored three wire connector. The terminals on the board should be labeled "comp", "line or L" and "def". You will need to put a jumper wire between the line and def wires on the wire connector (not on the board). Plug the fridge back in and your defrost circuit should be energized.
Good luck with this!

Everything in ref freezing up


1)check the temperature setting.it should be set on normal mode. 2) check if the ventilation in the fridge are blocked .there are two possibilities you will have to check 1)the defrost timer 2)the evaporator coil. How a common frost free defrost cycle works and the main parts. When the refrigerator is running ( cooling mode ) the defrost timer contacts prevents any power from getting to the defrost heater. When the defrost timer turns off the power to the compressor and fan motor(s) the power is then redirected to the defrost system. The defrost timer motor. Defrost timers:

------
the evaporator coils are located at the inner side of the freezer section.if the ice gets collected in the coil and the evaporator fan stops running then the inner system of refrigerator will get over cool and this problem happens.
--------
now to solve the issue .if to check evaporator coil is faulty or not there is a system.just unplug the unit from main power outlet then wait for 24 hours.then replug the power cord in the main power outlet.in 24 hours all the ice collected in between the coil and anywhere will get melted and then check out.if it works properly the problem was ice in coils.but if same problem then defrost timer needs replacement,you can get new timer friom
