I noticed it for several weeks and finally .. last night it came to me. Check and see how dirty it has gotten under there!
The entire front was clogged and vacuuming from the front wasn't working .. a bar trapped stuff in there .. I had to drop the front and get behind it to get a load out.
Now, it can breathe.
Took the back panel off also where the fan runs to blow air out .. that was partially blocked in the slits in the backing that were too small .. the big ones were not blocked .. so, I took my box cutter and just cut an entire row of small slits out and cleaned under the refrig where it sat .. it is running much less now and will last longer if the compressor hours are kept down.
Stuff you know but it does not come up often enough to stay in mind. I didn't know my front vacuuming was being blocked either.
If you get too far from the stone age .. things go haywire.
