Our repairman forgot to install the back two screws on the bos - control (AP3741097) and it appears that the screws for the front and back are different. Can you please let me know what the back screws are?
Answer Hi Willy. In the pictorial breakdown, it shows 4 - of the same part # 5304455650 screws. They are approx. 5/8" in length. Three of them go in the back 3 mount holes on the control lt, middle and rt. There is a separate U-shape cover that will butt up against the very back where the filter mounts. It will have 2 locater tabs in the front of this cover that inserts into the back area of the control box. In the back of this water tube cover is where the last #4 screw goes. However before this cover is secured as discussed, you need to install a screw just in back of the control box cover where the filter goes. It has a rounded mount tab locater where the screw goes into the upper cabinet. If you do not have this screw, use a 1/4" screw the same length as the others. Make sure you do not use a longer screw as to put a hole through the cavity body . Please let us know if we can assist further in the future. Thank You .
