Hi, I hope you can give me some guidance.
My Kitchenaid side-by-side, built in refrigerator
(Model: KSSC42QMS01, SN: Q54614745) is alarming. The "Call Service" light is off. Temps in the refrigerator and freezer
compartments seems to be normal and the unit is cooling.
The problem started as a soft ping with a growling noise (loudest in the freezer compartment) that coincided with the cycling of a fan/motor. The cycle was approx every 5-10 seconds. I opened the top of the unit and noticed the condenser fan running but would briefly lose power when the ping sounded. Condenser was very dirty so I shut off power and cleaned the coils.
Ping/alarm problem persists so ran the diagnostics (Filter reset button and power button on control panel) Test 1 & 2 pass. Test 3 sounds the alarm and briefly fails (code 02) then passes with code 01. Since the test is for Evap motor speed I'm guessing it takes a couple seconds to come up to speed. Step 4 successfully runs the condenser fan. Other tests pass. When forwarding past test #7, the alarm sounds continuously and flashes 37 in the refrigerator temp display. Now the alarm is mostly on (call service light still off). Google search of the problem points to the control board (2303934 apparently replaced by PS2360723). Unfortunately this board appears to be no longer available. Refrigerator was made in 2004.
On additional oddity, when I open the refrigerator or freezer door, the alarm turns off. Close the door and the alarm comes back on. Seems to be related to the box light as I can simulate this by manually activating the door light switch at the top of the door. Also I pulled the control board housing and verified the noise if coming from the buzzer on the control board.
Am I in the right ballpark with the control board? I may have found one on eBay for $300 but I hate to spend the money if the problem is somewhere else. Any help or advice would be appreciated. By the way, I'm very comfortable doing the repair and I have volt meter.
Thanks in advance. Tom
