Joe P Clinton , NJ August 04, 2019 Appliance: Whirlpool Gas Range SF395LEEB0 Whirlpool Range Sf395leeb0: Weak spark on the two right burners would not light that side. How to replace Range Spark Module. Replaced the spark module. The new one was longer than the old one. I had to remount it horizontally and had to modify one of the heat shields. Works fine now. It sparks much more rapidly than the old one. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
