    Default Kitchenaid Fridge Defrost Cycle

    Model Number: KSRS27CNWH00
    Brand: KitchenAid
    Age: 6-10 years

    Hi,

    I have a KSRS27CNWH00 side-by-side and the Defrost Cycle seems to be out of order. The evaporator is building heavy ice and the fridge is getting warm. I wasn't able to locate the wiring sheet anywhere on the unit. I'd like to run the onboard diagnostic procedure and obtain any error codes. I wasn't able to locate any diagnostic or repair info online.

    I've heard that the bi-metal can go out of order on these units when the door is left open for an extended period of time - that might be what happened here.

    Does anyone know where I can find the diagnostic procedure or a repair manual online for this unit?

    Thank you,
    al

    Hi al,

    Here's your tech. data sheet which has the diagnostics on it: www.applianceblog.com/manuals/Wiring_Sheet_2301270.pdf

    Go to step 6 and that will turn on your defrost heater if the defrost thermostat is working properly. Give it about 5 minutes and feel for heat at the bottom of your back panel inside the freezer where your vents are at.

    Thank You Jake!

    I ran the diag. and the heater did turn on. I'm wondering if the system may be working normally, but the defrost cycle is just not keeping up with all the moisture that's entering the fridge and freezer.

    What's the best way to test if the defrost cycle is working normally? Should I just check for heat a few minutes after I hear the compressor shut down?

    Thank you,
    al

    Ok al, since the defrost heater did come on, that means the problem lies in your control board that controls the defrost cycle.

    Its your control board thats malfunctioning and you'd to order a new one to fix this problem.

    Here's the control board for your model you can order here: Manufacturer's Number: 8201672

    Jake, thanks again for the reply.

    This is quite an expensive part. I'd like to check the system to see if the timer is turning on at all when it's supposed to before I purchase a new controller.

    I'm wondering if the defrost cycle is working when its supposed to, but just not keeping up.

    Do you know if there is a way to test or check the defrost timer function directly? Or perhaps there is a way to check it indirectly, such as seeing if the heater is turning on? When or how often should the unit go into the defrost cycle?

    Thanks for your help,
    al

    The defrost timer is integrated in the control board al.
