Setup

Temperature Calibration

Based on above, the fridge temperature was NOT calibrated. Increased temperature reading by 3°F.

Service Test - 211 Fresh Food Temperature Adjustment
Press the Refrigerator Temperature UP +/ Keypad or Refrigerator DOWN -/ Keypad to change calibration of Fresh Food Temperature plus or minus 1°F increments up to 6°F.

Levelling the Doors

Having the doors just right is important since it will ensure that the doors close properly. 

From the front to the back, there should be a 1/4 inch difference in levelness (higher in the front)... Adjust by the two adjuster foot pegs (front on floor).

Use a 1/4" socket and a ratchet to turn the adjuster foot pegs screws until the tops of the french doors are even with each other.

In order to get the doors to stay open and not close on their own, you need to ensure the fridge is level front to back and right to left. 

To adjust the doors:

• Remove the grill

• Adjust the two adjuster foot pegs using a 1/4" bolt driver. Check for level.

• Ensure Doors at top of fridge are even with each other and door closed properly and door's hinge flap is operating correctly.

Problems

Door Closure

With the fridge level, the door flap can sometimes fail to catch. To address this, I added a spacer between the catch(bearing block) and the cabinet which brings the catch down slightly.

Freezer is Cold but Refrigerator is Warm

https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Refrigerator/58-129--/Bosch-Refrigerator-Freezer-Is-Cold-But-Refrigerator-Is-Warm

Things to check (Top 6):

• Dirty Condenser Coils
• Malfunctioning Condenser Fan Motor 
• Defective Evaporator Fan Motor 
• Faulty Start Relay or Capacitor
• Evaporator Frosted Over
• Malfunctioning Temperature Control Board

Round 1

Observations

• Freezer is at temp(0F) but fridge is warm(57F).

Actions

• Checked the condenser fan and it didn't appear to be running.
• Removed and tested it by applying 120v to the fan contacts. Seems to work fine.
• Replaced and it has been working fine since.

Questions

• Is the fan working intermittently?
• Could there be a thermostat/control issue? 
• Is it possible the door was not closing properly and the french door's door flap was not engaged?

Round 2

It Happened Again

• Checked condenser fan and it was working.
• Not the door flap
• Cycled the power and no change
• Turned off for 30-60 minutes and it started up and cooled!
• Could be:
  • damper freezing closed due to bad fridge temp calibration
  • defroster
  • defrost timer
  • damper stuck
  • evaporator fan? (heard it, so unlikely unless the fan blades are messed up)

Current Thought 

I think the temp was getting too cold in the fridge compartment causing the damper to freeze closed. Temperature displayed on fridge was 3F higher than actual. Setting the temp to 38F was equivalent to 35F(1.6C). Fridge was probably dipping below zero from time to time.

Fridge temperature was calibrated and set at 5C. We shall see if it happens again.

Few Days Later

Seems to be working fine at 5C. Graphing the temperature seems to show a fluctuation between 3.2 - 5C. Averaging at 3.8C.

The perfect temperature to keep your food fresher for longer, and avoid ice, is 37F or 2.8C.

Reducing temp to 3C. 

Round 3

So, it stopped working again. Temperature too low?

• Tested Damper Motor - Failed to Open
• Tested Evaporator fan - Passed
• Tested Condenser fan - Passed
• Ran the damper motor again and it ran the second time.  

Current Thoughts

I think the damper is freezing closed or the damper motor is flakey.

Increased temp to 5C.

After watching the YouTube video https://www.youtube.com/watch?v=0EZnLvuCN9o, I can say that our motor is noisy....

Should probably replace it.

I've ordered a replacement.

While waiting for the new damper motor assembly, I ended up removing the damper and cutting off about 5mm of the foam from the bottom of the door. 

Worked fine until the replacement arrived (about 4 days with temp set at 5C)

Replaced part and set temperature down to 3C. Wait and see.....

Damper Repair

Remove cover by pushing up taps from the bottom and then slide cover down.

Unscrew mount and remove.

Disconnect power and unclip motor.

Ice Maker Repair

The ice make arm was missing so I made a new one... Time will tell if it works.

Who really makes the  ice maker?

Observations

• part number on Bosch supplied ice maker is W10683115 (Whirlpool)
• Apparently W10683115 was replaced with W10886931.
• W10886931 Parts Breakdown - https://www.reliableparts.ca/lookup/237899/1612272#diagram
• Arm: W11559683 ~ $54

I successfully replaced the arm with this part:

Wirlpool WP67004028 - Amazon ~$20
