[video] Troubleshooting a Kenmore-Electrolux Dual Fuel Range F30 Error Code

Samurai Appliance Repair Man

681 views

This dual fuel range was flashing an F30 error code. The tech sheet says this points to a problem with the RTD (temperature probe). A parts changing monkey reading only the error code description without looking at the schematic replaced the RTD only to have the exact same problem: F30 error code. Watch how a real technician uses both the tech sheet and the schematic to accurately diagnose the problem without guesswork.

That's something I've never seen before in my 34 years doing appliance repair - I can't ever recall seeing an Electrolux/Frigidaire or any other brand have a Hi-Limit Thermal CutOff in the RTD sensor circuit - from the circuit board it appears from the date I saw in the video this is a 2004 or there about range.

Excellent comment! I had never seen the RTD-bimetal combo either. It’s a good case in point example of why we should always review the schematic to see if there’s any weirdness or surprises in the circuit of interest that we’re troubleshooting.

Seen that 2 times so far.  The first one sure threw me for a loop. Tested it at control and it was Open. ( thought it was odd for it to fail completely open). Went to test at the part, found the tech sheet found it on diagram, and and noticed the bimetal there, and found it open.

The troubleshooting guide of the manual did state:

#3 Look for broken Security thermostat (open)

So I would also add that the original sin could be to not FULLY RTFM.  I am guilty as charged sometimes, not reading to the END of the list of possibilities for a given error.  But yes, the schematic makes this absolutely clear.

I rarely look at service manuals except for disassembly procedures and sometimes getting specs that are not included in the tech sheet. The tech sheet and schematic are almost always sufficient for troubleshooting. And reviewing the schematic takes a fraction of the time needed to page through a service manual. Finally, Electrolux no longer makes service manuals available to non-authorized techs so it would be wise to learn to not need them (or at least need them less).

My bad, I meant the tech sheet, or whatever document that you were using in the video.  This is a great example where the MORE likely issue is not listed first.  I have hit this a few times where it has bitten me good...ie   assumed that the last listed possibility is the least likely, they don't seem to be listed in order of possibility occurrence.  for example I have seen this in tech sheets...

DRAIN ERROR:

  1. Bad Pump
  2. Obstruction in sump
  3. Clogged drain hose
