ok guys got one for you.
i looked at a domestic frige today.
from what i can tell it has had a new timeclock installed in the last couple of years. other that that it has not had anything done to it in its approx. 10 yr life span.
the nameplate said
the problem is that the drain for the evap is freezing up and then water overflows and runs on the floor. there is no drain heater nor does it look like there ever was. the back of the freezer has an alluminum panel that comes down and then becomes the drain pan. my thought was the heaters will heat this panel when in defrost hence heating the drain line. the timer did not say how long the defrost was although it did say 10 hr. (wish i had the m# of clock now) i am wondering if the clock does not have a long enough defrost which would not let the drain get warm enough letting it eventually freeze over. anyway the homeowner had it thawed out a yr ago by another contractor and i would love to repair but have been unable to locate manufacturer or anyone that knows anything about this make.
any help would be appreciated!
