Defrost issue old magic chef

04 November 2013 - 01:17 PM

I have a issue that i've research well and think i may know what the problem is. But the model has been out of production for several years and i can't seem to find the parts. It's the old cold freezer warm fridge issue, it's not defrosting. I pull out a hair dryer every 2-4 weeks to manually defrost it. I have detrmined it is probably the defrost thermostat. Tho it could be the timer. I ohmed out the therm and it's been a while so i forget, but i think it was open even after leaving ity in a glass of ice water, mostly ice for a good while. But i may be worng as thats been a while. I assume it is suppost to close only when it gets cold enough, so if it's not closing it won't turn the heater on. I also thought it couyld be the timer because i manually turned it till it just clicked and it went back on in just a few minutes. But i concluded maybe thats because since the thermostat is always open it decides it's all good and starts the compressor again. But i may be wrong as i am only just learning this stuff.


So i have 2 questions. 1-what does it sound like the issue is to you, and 2- i don't believe theres a temp written on the thermo so how can i determine what substitute i can use? They are no longer made. I found one on a site that looks the same with the same plug on the end which i found by searching with the model # of the fridge, MCBR1000W. But they had 2 types, type a and type b. Type a looks totally different so it's type b that looks like mine, but every search i do the only one i can still find thats availablle is type a. Heres the one i have... http://www.appliance...1411298blk.html Of couse as you see it's out of stock because it's no longer made.


I will look at it tonite and see if theres a temp rating on it, but i don't think there is. So how can i determine what to get as a sub if i can't find one ? I found one that looks the same but no plug (not a problem, i can splice)  here... http://www.repaircli...0225581/1872722 But i have no idea whether it's got the same rating.


Anyways, I think the timer is available but need opinions on which part it is thats causing this, how i can definately test both the therm and timer to be sure, and how to look for a sub thermostat if i cannot find the temp spec. Thanks in advance.
