My Magic Chef refrigerator 10 cubic feet makes a loud knocking noise.

This answer was rated:

We have a little 10 cubic foot 2-door Magic Chef fridge at work. Around a month ago, a very loud knocking noise started coming from the back of it. When I'd open the fridge door, the knocking would stop. The freezer is working great, but the fridge section isn't cooling anymore. I'm supposed to be in charge of fixing this! Is it something I have to call someone out to look at and fix? Thank you for any help.
sounds like it may be a evaporator fan issue. can you get me the model#? thanks Bryan

mbcr101W, looks like from what i can tell online. I can't seem to find a model number on the fridge itself.

ah. just found the owner's manual. it's model #MCBR1000W

well i found what I believe is your problem but you may just have to defrost problem and the blades on this fanPart(###) ###-#### width= were hitting ice , can you tell me if there is any frost on the back panel inside the freezer section? let me know thanks Bryan

I don't see any frost on the back panel. The blades seem to be whirring away though.
ok but its not cooling in the fresh food section? do you feel any air comming through the vent into fresh food section? you could be frozen behind the back panel or in the air vent to the fresh food section. can you remove the back panel in the freezer section and check for allot of frost on the coils? let me know , thanks Bryan

Okay. I removed everything from the freezer, and at the bottom right corner there was frost build up, right where the panel can be removed. So I unscrewed the panel. Try as I might, I can't seem to pry off the panel completely. Only the top section is loose. So I can't really see what's going on in there, but you were right about the frost. Also, I don't feel any air coming through the vent in the fridge section.

Should I wait until it's had a chance to thaw out before trying to pry the back panel of the freezer off? I pulled so hard I cracked the lower portion of the panel.

you can unplug this and let it defrost for around 24 hours with the doors open or you can take a hair dryer and defrost it.the panel is frozen to the coils. dont force it. more than likey you need to replace either the defrost thermostat Part(###) ###-#### width=or the defrost timer. Part(###) ###-#### width= you can get these here, let me know , thanks Bryan
