SOURCE: m#13qc-042k system will not go

There is typically a set of jumper pins on the defrost control board that allow the system to go into defrost after 30, 60, or 90 minutes of run time. There are also two bare pins that say "test" on them. While unit is running, approx 15 min or so in heat mode, short those two pins together for about 5 seconds, this will force the unit into defrost mode. If it still does not work, you might still have a defective board. Depending on the humidity in your area, that is how you determine the defrost interval.

Samsung refrigerator defrost problem


Check the defrost drain hose. If it is plugged, the water from defrosting has no place to go, so defrosting doesn't do much.

Also, make sure you have power to the defrosting circuit (you may have a problem with the wiring). The simplest and safest means is to do a continuity check of the wires between the control board and heater with the refrigerator unplugged, or unplug the heater connection to the control board and measure the resistance of the heater through the connector(s). If it is open or very high, examine the wire terminals for corrosion. If the defrost control board is separate from the rest of the refrigerator control system, check for power coming into the board.

Coleman php030h1321a UNIT RUNS OUTSIDE, BUT NO HEAT INSIDE. I JUST HAD TO DE-ICE THE COILS (ALL 3 SIDES) outside. It started back with the heat for 2 hours and cut back to throw recycled cool air back into...


It sounds like you have a bad defrost board or defrost sensor.
Will the unit defrost on its own?
If you take the panel off and find the defrost board, there is two pins labeled test or speed up.
Take a screwdriver or something and touch these two pins together with the unit running in heating and hold it for about 10 to 15 seconds to see if it will go into defrost. If it does then the board is OK.
Next you need to check to see if you have a coil sensor by looking on the board at the wires you will see that the wires are labeled on the board. Two of the wires should be labeled either coil or sensor.
Some of the sensors are thermistors and some are switches.
If it is a switch then you can disconnect the two wires and put a jumper across the two terminals labeled coil or sensor and with the unit running in heating and touching the speed up pins together and holding it for a few seconds and if it goes into defrost you have a bad sensor.
If it is a thermistor you can’t do this because you need a certain ohms resistance across the terminals, it won‘t hurt anything if you do jump the two terminals, it just won‘t go into defrost.
If no sensor then you have a timed defrost you should see a jumper wire and some pins labeled 30 - 60 or 90 meaning minutes. If the jumper is on 90 then move it to 60 or 30 and see if this will help this board also has the speed up jumper. With the unit running in heating by touching the two pins together it should go into defrost, if not the defrost board is bad.
If the board checks out OK then you also could be low on refrigerant.

About the only thing I can suggest you check is the initiate termination thermostat (assuming your Heat pump works with one of these). It will be identified by 2 wires going to it and it will be clamped on the line (Not brazed on or screwed on). Now there will also be a reversing valve which has 4 tubes going to it and 2 wires. and it could have high, low, pressure switches that have 2 wires. This thermostat is usually mounted 1/3 to 2/3 way down on the coil and is suppose to be mounted on the "U - Bend" of the out door coil tubing. It usually resembles a pancake and will have a wire or metal clip that holds it securely on the coil U bend. Make sure it hasn't fallen off or come loose. This can cause your heat pump to miss its required defrost.

You can try this also. Some defrost timer boards have a set of "test pins" you put them together with a screwdriver or a piece of wire for a few seconds to initiate a defrost. It defeats the time logic in the board It should go on into defrost and stay in until the coil is cleared of frost and or about 10 minutes which ever comes first. If it comes out right away it may be the termination switch I talked about above. It could also be the board. To check out the thermostat locate the 2 wires going to it from the board. pull them off the board and retry it. Sill goes right out of defrost then jumper the 2 wires together and try it again. If it still comes out this time it most likely the board. If it stays in defrost either time when removing the wires or jumping the wires its the thermostat.

If its anything else; Well Its a little complicated and unless you understand the heat pump /refrigeration cycle and the need for defrost and how the defrost is limited and initiated, well Id say yep...you need a pro.

Hope this helps you. If so please rate me as high as you can. Thank you for using fixya and good luck.
