After unplugging the refrigerator, I used a hairdryer to melt the ice sufficiently to be able to remove the freezer rear panel with a nutdriver. I also removed the ice-maker for easier access to the components behind the panel, using a nutdriver. Once the panel was removed I melted more ice at the bottom of the evaporator housing. After partially melting the ice in the drain tube, I poured hot water down the drain tube until it cleared, signaled by the sound of the water dripping into the drain pan. I next removed the clip-on Bimetal thermostat from the copper line going into the evaporator and snipped the two wires to remove it. I installed the replacement thermostat with crimp-style connectors and pull-tested them. I also replaced the timer board that is located below the freezer, below the top shelf, using a nutdriver. I replaced the circuit board as a precaution that the thermostat may not have caused the problem. I didn't change the heater inside the freezer as it checked out to have the same resistance as a new one. I tested the removed thermostat using a glass of ice water but it remained in the open condition, using an ohmmeter. (I later checked that thermostat after the freezer was running and it did close, and returned it to the open position by heating it under the hot water faucet. I suspect that it didn't work properly, or the timer control board was faulty). After re-installing the back panel and ice-maker and plugging the refrigerator into the power receptacle, it worked very well, and has done so since the repair.
