Hello.

The refrigerator started making noise sounding like the fan behind the panel at the

back of the compartment. Ice build up, I'm sure, from the information I've found so

far. Problem is, I need to know how to get that panel off without destroying the plastic

and foam and whatever else is back there to get a look. Doesn't look possible but the

parts aren't too expensive.

Anyway, the fan stopped making noise will no help from me, and, in fact, doesn't

seem to be working at all any longer.

Questions are:

Is the fan necessary to cool the refrigerator compartment or just for defrost?

Should the fan run continuously except for open doors?

What's the easiest way to get to the fan to check it?

I have a request for the manual in the manual forum.

Thanks for the help,

Tony

Evaporator Fan usually should only run when the Doors are CLOSED and the compressor is running,

(on some, the evaporator fan will run even with the door OPEN).

Needed for Fridge compartment cooling.

Sounds like the Fan Blades are hitting the frost on the Evaporator.

The Defrost Heater may be bad.

Thanks. I have received the manual.

Next question, Sensei.

How do I upgrade to Apprentice? Can't seem to do it from the menu drop down item.

thanks again,

Tony

PS: I'll be back after poking and prodding this thing for a while.

Thanks. I'll be checking all of that now that I have the manual.

RegUS, I'm sure you know this is wrong but just mis-typed?

This is a glitch from when we migrated the database from the old forum software (WowBB) to the current one (Invision Board). Users who were in the database at the time of the migration are unable to see the subscription options. The only work-around is to simply create another account and then the Apprenticeship subscriptions will appear for you.

Thanks for all the assisstance.

I already found out that the fan runs with the doors closed and compressor running.

Got the front cover off, working on the foam. The whole thing is a solid block of ice

so I need to wait for some defrosting to take place.

Is the parts offerings here on the site associated with the site in any way? I'd like

to buy the parts here, if necessary. If not, any recommendations?

Right now, it's looking like the plastice evap cover, foam, maybe the fan if it's damaged

by ice and most likely some sort of sensor and the defrost heater. I'll know exactly once

enough ice has melted to get the foam cover off.

thanks,

Tony

There appears to be 5 circuits to the evap compartment:

Fan

Ambient temp

evap temp/frost sensor

evap heater, and

bi-metal thermo switch.

The fan works with the red and black but no the white and black-

don't know if this is normal yet.

both temp sensors read the same for the ambient temp and

appear normal.

Bi-metal has continuity as does the heater .

Searching the manual for clues. Please let me know if I've made and

incorrect calls on the equipment.

thanks,

Tony

Excellent.

Can't find the spec for the heater to make sure it's out of tolerance. I'll look in

the manual again, but if anyone has it handy, I'll take it.

The only other variable is the 3 wire evap fan motor. Red, white and black wires.

Fan works on red and black but not white and black. Is the third just a speed sensor

wire?

Thanks, yet again,

Tony

1) Heaters don't "get out of tolerance" .. either they work (a few hundred OHMs) or they're "open"

2) yes

Outstanding.

Making my final checks and working up a parts list.

after manually defrosting,

may need to see a picture of the frost pattern after the Compressor has been running an hour or two ..

OK, here's the deal.

With the help of the manual (thanks for that) I was able to disassemble, test and reassemble the Refrigerator

evap compartment and then use the front panel to check for errors. There were no errors on restart and all

the items tested OK. The attached pic is the evaporator after running for about 5 hours then using the defrost

cycle for just a few minutes to test the heater. The frost buildup was consistent over the whole evaporator. No

indication of any problem area. The only thing I found out of the ordinary was the evap temp sensor was laying

in the compartment unattached to the coil tubing. I snapped it back on at the top, middle and I'll see what happens.

No parts needed although I did break a couple of the tabs that hold the plastic cover to the foam insulation.

I will order this piece and a backup sensor and heater for the next time, should that occur. Seems it will, eventually.

Thanks for the help, it is appreciated.

Since I can't upgrade my current username, I'll be back shortly as tmfixit2.
