Some good repair videos on Youtube help me hone in on the problem.....a slow reacting ignitor. So I ordered the ignitor and a new probe. The parts come about 3-4 days later. I installed the ignitor, did not need to install the probe and did some temperature offset adjustments and now the oven word just simply great. My wife had gotten discouraged with the stove after a number of "fallen" cakes graced our table. She has not tried any cakes yet but we know we have a much faster reacting temperature control and more accurate temperature indications in our Frigidaire now. Maybe the "desert deprivation" will now end with a well repaired oven. We will see.
