Puddle on floor in front of fridge

"Hi @ron_co ,

You could try cleaning the tube with a mixture of vinegar mixed with warm water. (75% water, 25% vinegar)

Block the outlet of the drain tube above the tray and then pour down the drain hole till it backs up to under the evap unit. Block the top of the drain and allow to stand for 10-15 minutes and then clear both ends of the tube to allow it to drain out. Flush with a measured amount of clean cool water and confirm that it all gets to the tray. Also check that it doesn’t take too long to drain when doing this i.e. doesn’t slowly drip out

With the defrost action the water only drips down the tube. As the ice melts, it only drips off the evap unit and then makes its way to the drain hole. It doesn't all go at once. Also it may be that occasionally some might freeze at the entrance of the drain when the defrost cycle ends and the cooling commences again but it should melt first and then flow down on the next defrost cycle.

According to the mini manual that I linked in your previous question regarding this refrigerator, the defrost occurs every 10 hours and lasts for 21 minutes, so presumably you just may have to wait and catch it at the correct time.

There is also a ""service jig"" mentioned which seems to connect around the defrost thermostat but I don't know what it entails or how it works.

If it simulates the defrost thermostat operating/releasing and allowing the heater to turn on/off I can't see how it turns off the compressor, unless the compressor has to be unplugged at the same time or the temperature control altered to supply power to the heater(not mentioned).

Otherwise to me this would mean that the evap unit is still getting refrigerant being pumped through it but it also would have a heater trying to melt the ice on it so that doesn't make sense to me i.e cooling and heating at the same time"
