Robert A Schaumburg , IL December 10, 2016 Appliance: Samsung Microwave SMH7185STG/XAA Samsung Microwave Smh7185stg/Xaa / : Lower handle cap broken. How to replace Microwave Earth Door Assembly. Ordered (2) Handle caps and (1) Earth-Door new Wave 2 clip. Wasn't sure of the need or purpose for the Wave 2 clip but for a little over $4.00 figured it was worth a chance. Only had to partially remove the inner trim with a putty knife.to access screws (videos helpful) because I had a stubby Philips screwdriver. Removed handle assembly from door. Top cap had the wave 2 clip inserted but the bottom cap did not have one. Maybe that's why it broke. Inserted the wave 2 clip I bought into bottom cap, reused the top cap and clip and reassembled. Now have an extra cap should one break. Did the fix in front of my wife of 41 years and finally she thinks I'm a genius. It took me longer to write this than to fix the problem. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
