How do I set the defrost times?
Unit is a Thermoking SBIII SR50 with Multitemp.

Also, when I run it using the electric standby motor, should the Cycle Sentry be turned off to make it run continuously?

Thanks for any help!

guarded access, turn on fridge, turn off cycle sentry, press TK button and Clear button same time, scroll thru to defrost durations should read something like 6 then 4 then 6 the DDUR 45, the 6 numbers are frozen range defrost timers if i remember correctly. you'd need the manual to show you exactly how to change the times.

on standby its up to you how you set it, if you need the constant airflow leave it on continuos.

TK button and clear button at same time had no effect. :confused:

Cycle Sentry was in OFF mode. I may need the exact procedure sequence to make sure Im doing it correctly.

4
dEF nA (?)
2
