I have an upright Kenmore freezer, model number 253.21041103 There is a drain in the bottom of the compartment. Water drips out of the evaporator and freezes in the drain. Then ice collects in the bottom of the compartment. It is defrosting (obviously) I ohmed out the defrost heater it was around 23 ohms. Drain is not plugged. Water flows freely after I melt ice in the tube with hot water. There was a plastic cap on the drain end. I pulled it and inspected for gunk, it was clean.
Thermostat is set at "4"
Could this be a defrost timer issue?
I saw some mention of a drain heater on this forum, is there one made for this unit?

Did you run hot water down the drain to see how fast it flows to your drain pan?

Pour some bleach down the drain hole too.

Actually, I don't see how this is supposed to work. You got water dripping onto sub-zero sheet metal and it freezes there. Some of it gets into the drain and some seems to freeze right away.

The defrost heater is suppose to warm up that metal drain trough where the water drips too and down the drain hole, you can possibly lower the defrost heater closer to that metal drain trough.

If I need to do a modification to correct this, what about a drain heater? Is there something like that available for this unit?

I don't know what that's gonna do for me. That looks like the strap that holds the htr up. If I want to try and lower the heater, I think I would have to remove the straps.

No, that strap attaches to your heater and goes down in your drain hole.

Look here:

Awright, the part came to my home town and then it got shipped to SD, then it got rerouted back here. I was correct, that is the strap that holds the heater up against the evaporator. I made an attempt to use it as depicted in the photo but that was no good. Can I get a refund on that part? Pretty expensive piece of aluminum that was not what I needed...
Anyway I lowered the heater a bit and wrapped some copper wire around it and routed that into the drain hole. That wire gets very hot and seems to be doing the trick. I may have to remove the cover again later to make sure the evaporator is still defrosting properly.
