Sears/Inglis model LT74182 refridgerator, 17 cubic feet, top freezer, 1983
I noticed that the defrost timer is making some noise. It is sort of a tap tap tap, sound of gears and or motor running. It is not excessively loud.
The defrost timer works as I get a bit of water in the evap tray underneath, and I did mark the knob on the timer with a dot if white out and it does turn.
This is the 3rd timer, as the first was replaced under wsrranty, 2nd maybe 20 years ago.
Defrost timer has numbers on it K99A61, old paper work says 8 hour 26 minutes cycle
1.) Should I replace it or let it go as it works? It is not too noisey and the fridge is in the basement. (If it is not broke, don't fix it? LOL )
2.) I cannot find a K99A61 timer ... if need be.
