Question about Sanyo SR-981 Top Freezer Refrigerator

2 Answers

Freezer works fine, refrigerator loses the ability to cool until barely cooling at all.

I inherited this fridge in a trailer. When I first got it the freezer was working and refrigerator section was not cooling. I unplugged the unit and left it for about a week and when I turned it back on the unit was cooling normally. It has slowly lost the ability to cool again. I figure that it has something to do with the defrost elements not working properly but I can't find any service information for that unit to know what needs to be replaced, how to check it or how to replace the parts that are bad. How do I know what the root of the problem is and what parts to replace?

My ref runs smoothly at first but until it reaches -9 centigrade with compressor running with refrigerant flowing thru the tube, then it slowly loses its cooling ability but with compressor still running. the compressor continues to run for 10-20 minutes but with rising temp( i have a thermometer inside the freezer), the defrost timer kicks in for 5 minutes, then the power shuts off. After another 5 minutes, the compressors kicks in again, full power, and complete the cycle again. the temp goes to -7 to -9 C. The problem is, I can't get/make ice from my freezer even if i adjust the defrost timer from minimum to maximum

First thing I would do is remove the back or bottom to expose the evaporator coils. If the coils are all iced over you do have a defrost prolem. You ill need to locate the defrost timer and most times there in the fresh food section. Where on your model I cant tell you but it will have a slot for a flat head screw driver to turn the shaft. Turn it untill you hear a click. That will put the timer into defrost.Then check and see if the heater is working. if not you need to check the heater and the defrost terminator, The trminator is a small round disk with 2 wires on it. you will need to ohm it out to make sure its not stuck open. If it is thats your problem. If not ohm the heater. if thats good replace the timer.And are you sure the evaporator fan is also working? If it is not you will not cool the fresh fod section.There should also be a schematic maybe on the back of the unit or on a tech sheet in the back or behind the kick plate. Good luck

Ro@hotmail.comtemp fridg& frezer will chang 30 to 40 degrees if you open either door it will take a long time for for temp to drop


The compressor is the part which cools the refrigerator.---------- First i will explain the working procedure of your sanyo refrigerator.---------- In the refrigerator, there is a part called compressor, the compressor is the part which cools the freezer section, When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold.--------- So the freezer section cooling/ freezing is must.If freezer is not getting properly cooled or not getting cooled, then fridge section will show the low or no cooling problem.--------------
In your refrigerator, its quite possible that compressor is got weak, nor complete faulty but little bit weak.So when you open and close the fridge or freezer door , the compressor is not that strong to maintain the required temperature.So its working hard to cool inside temperature, but its not doing it quickly as it should.---------.---------- In the compressor there is a refrigerant called FREON.With the help of this Freon the compressor cools the freezer section.Freon is a gaseous type cooling agent.The compressor will stop cooling when coolant gets leaked from its chamber.--------- Again recharging the Freon is possible, but the cost for that recharging is approx the cost of new compressor.So its always advisable to get compressor replaced.Because new compressor has warranty for few years.------------------ You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- ----------------
There is manual reset procedure, sometimes the ice gets frosted all over and blocks the ventilation's for cool air to pass from one section to another, and this also causes problem.So directly going for compressor inspection, before that you can try manual reset procedure and see if that helps.---------

The manual reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take approx 4 to 6 hours for your refrigerator to regain its regular cooling/ freezing .So after 4 to 6 hours check , Is the refrigerator cooling properly or is it taking time or temp is dropping once you open close door. If this problems are not noticed, then reset procedure has helped.------- But if same problem is noticed after reset procedure is followed, then you can get the compressor checked. -------- This should help. Thanks.Helpmech.

This problem is related to defrost.

Try manual defrost reset procedure: ----

First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced. you can get the required parts from online sites like:---

www.repairclinic.com or from searspartsdirect online site.---------

If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located.

Frig stopped working but freezer is good? Help... I am handy.


When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.
---------------

Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 24 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section.

Refrigerator not cool, freezer ok


Either the freezer continues to freeze up (most likely due to low refrigerant, due to a leak), or there is an obstruction between the freezer and the refrigerator (refrigerators get their cooling from the freezer).

Given that it works after you defrost it, I'm going with low gas. Call a professional to see if the leak can be fixed. If the unit is more than 10 years old, just get a new one.
