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 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
