Ian G Plymouth , MA April 25, 2015 Appliance: Electrolux Wall Oven EW30EW55GS5 Electrolux Oven Ew30ew55gs5: The liner of my electrolux wall oven buckled and shorted out the hidden element under the base of the liner all resulting from aluminum foil. How to replace Liner. Replacing the liner was not difficult, you only need a screw driver, but it took a long tome - for me about 8 hours. You need to disassemble at least 70% of the oven in order to remove the liner. Take plenty of photos and bag and tag the numerous screws you need to remove. I would also recommend tagging connectors that also need to be disengaged. This job should only be attempted by personnel with mechanical and electrical dexterity. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
