Coil should have continuity. Defrost limit should have continuity when cold. Check w/ meter. If checks ok then defrost timer is probably out. I cannot see your reply due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

Why does my t-24-gc glass chiller keep freezing up to the point the ice hits the fan?


Check the defrost timer. Turn the small slotted knob on the side with a screw driver until the unit turns off. this will force it into a defrost check the defrost heater strip if it is getting hot then replace the defrost timer if not then check with a volt meter to make sure your getting power to heat strip. If you are getting power to heat strip but it is not heating up then replace the heat strip. also before you force it into a defrost check the defrost termination switch with a meter make sure you have power going to it and through it. It will be mounted on the evaporator coil a round therm o disk with 2 wires on it should be a red and pink one. If you have power going to it and not through it then replace it. This cuts power to defrost time if it gets to hot at coil during defrost.

Hi, Our refrigerator has stopped cooling and I desperately need to try to fix it myself. Lights still come on. Fan or something is still running but the freezer still works so I thought maybe that's what...


There is likely a problem with the defrost circuit or cold air circulating fan (but could be a low freon charge or other problem). The freezer compartment has the cooling coil with defrost heater and a fan that pulls cold air from the freezer and blows it into the fresh food compartment; based on the setting of the thermostat in the fresh food compartment.

When the defrost heater fails, the area that the cooling coil is located in eventually turns into a solid block of frost and ice. It becomes impossible for air to be drawn across the cold coil, cooled and blown into the fresh food compartment. The result is a rising temperature in the fresh food compartment - and eventually in the freezer section, too. Since the fresh food compartment contains the thermostat and the temperature never gets low enough to satisfy it - the compressor runs non-stop. That is, until the defrost timer kicks in to shut it off for 20 minutes or so.

The first thing to do is to manually defrost the freezer by accessing the cooling coil after emptying the contents of the freezer. This can be a pain in the neck to remove racks, shelves, ice maker, etc. to get to the back wall of the freezer, behind which the cooling coil is found. If you expose the cooling coil and it is encased in frost and ice it is a problem with the defrost circuit. If it is not - the fan is suspect. If the fan spins, check for a blocked path between the fan and the fresh food compartment. Defrost by placing a heat source in the freezer or directing the output of a blow dryer at the coil. If you're unable to access the cooling coil, you can simply empty the freezer and defrost it with a heat source. it will take longer to melt all the frost and ice, but it will work.

If it is a defrost circuit problem, you'll need to check voltages and continuity on the defrost terminator & timer and defrost heating element, fans, etc. after completely thawing the ice & frost.

This job isn't a good first time DIY job due to the danger of freezing skin, etc. due to possible exposure to freon in the system and the tight spaces you'll be working in with live voltages. You might want to call a pro after you've defrosted or put up another fixya request if you decide to dig in on your own and need specific help with procedures, locating parts, wiring diagrams, etc.

I hope this was a good starting point to help you decide whether to go forward or not on your own. Good luck!

Refrigerator not very cold. It's a 2000 model and it just started not being very cold despite turning the thermostat down.


you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

Problem with the unit not defrosting. How do I know which part is the problem? Thermostat, heater and Bracket assembly or mother board. Is there something else I should be looking at? Thanks Dan

Remove the lower freezer panel end then remove the rear panel . Remove the ice under bottom panel . Useing a hair dryer , heat the aluminum tray under the coils until you see the black drain hole . Continue defrosting the hole until free of ice . Could help useing a small screwdriver into hole . Even hot water into hole could help to clear . Once water will drain into hole , use a small hose inserted into hole and blow thru it to clear and obstruction in the line (line is inside the cabinet , unaccessable ) , Then find about a 14-16 gauge aluminum wire , aluminum fence post tie , aluminum ground wire , and insert it into the hole until resistence is felt . Wrap the top portion about 1 turn around the calrod (black) heating element and cut off the rest of the aluminum wire . The element will transfer heat to the wire during defrost , to keep the drain hole clear of ice .

I have an admiral model HMG 67184 side by side and I can't figure out why my freezer section still works but doesn't get cold enough to make ice cubes and the other side doesn't work at all. I do have...


1. Get the Food out of the Ref and Freezer. Unplug the power cord from the wall.
2. The cooling coil is in the back wall of the freezer side. Working from inside the Freezer.
3. Remove the back plastic cover to expose the cooling coil. It's called the Evaporator coil.
4. Use a hair dryer to melt all ice off the coil.
5. Put it back together. It should work for 3 - 5 days now at least.
6. Put a thermometer in there. After 24 hrs. the freezer should be 0 to 10 degrees F. and the Ref. side 37 to 44 degree F.
7. Check the door gaskets for tight fit, using a dollar bill for a gauge.
Shut the door on the dollar and try to pull it out in several places.

If it ices up again in a week or two, you have a defrost heater problem. There is a electric heat strip around the cooling coil. This heat strip comes on about 10 minutes every 8 or 10 hours. This heater melts the ice off the coil. There is a clock timer device under the ref. that cycles the heat strip. You may have a bad clock, fuse device or burned out defrost heater strip. The cooling coil must be ice free to work properly.

Samsung French Door Refrgerator - New


Only two months old? Couldn't you complain to the store?

The way the defroster works is this: There is a defrost timer under the refrigerator. (I'm guessing based on other brands.) That turns on the defroster about three times per day. The defroster is a heating coil with the freezer coils. It heats that until the defrost thermostat gets warm; then it quits defrosting.

My guess is that the defrost thermostat doesn't turn off the defroster... that it continues defrosting until the defrost timer turns the defroster off.

So if you want to fix it yourself, dig into the defrost coils. I don't know where to look on a French Door refrigerator. Find the defrost thermostat, an inch wide unit with two wires. Test it for continuity while it is warm. There should be none. Frozen there should be continuity.

Hope that helps.
