Question about Refrigerators

2 Answers

My 8.5 year old MZD2766GEQ has been working fine now for a couple of weeks, but I'm still not confident that my problems are over. Two weeks ago I experienced my fridge side getting 'not so cold' and made several inquiries to find a resolution. I took the back panels off rear wall from inside the freezer and the radiator looking park was encased in frost/ice. I took a hairdryer and melted everything off, then kept the doors open overnight. The next day I plugged it back in and by dinner time, things seem to be working fine. Curiosity got the best of me because I've read so many reports/problems/solutions on this website. I took the panels off the inside back wall of the freezer, and with disapointment found frost beginning to build again. Is this headed for a repeat of solid ice build-up? Like I said, things are working fine now, but is that radiator looking part suppose to remain clean and frost-free? Please tell me what I should do at this point. Thanks!

The coils should get a coat of "frost" but not ice.
If there is ice that soon - check the door seals to be sure they are sealing out humid air properly... and also the defrost timer may be faulty. It may not giving the evaporator (radiator behind the panel) enough time to melt the frost... or not shutting down at all.
Your fridge has an adaptive defrost - which means it is electronically controlled.

CLICK HERE to see/purchase a new defrost board.
CLICK HERE to see/purchase the defrost heater assrmbly if the adaptive defroster IS in fact sending out the proper voltage - the heater may be burned out.

Some basic troubleshooting and electrical knowledge is required to test these parts.

Thanks!!

    There are refrigerators that have a mechanical defros timer - and some with electric (adaptive defrost timer).

    In your case it is electric, and only have the board. Sorry if my original post was confusing. i was giving the cause for all refrigerators (in general) and then specified your was electric.



    Thanks!!

RCA 50" - Convergence problem and now "Popping" + no picture


The high pitch popping that you are hearing is arcing in the high voltage circuit. I would not suggest a repair on a set that is this old. Convergence repair plus a high voltage problem could run around $500-$600. But it is your call on the repair, I can only advise.

I hope this helps you.
Thanks for using FixYa

Food and water freezes but ice cream is soft


Check the door gasket seal.
Open the door for a few seconds and then close.
Immediately open the door again, and, if sealing properly, it should take more pulling force to open the door.

A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks
