Control knobs on Gorenje range are hard to turn or feel loose and wobbly.

Safety first: For gas models, turn off gas supply before removing knobs if you will access taps.

• Inspect knobs: Pull off the knobs and check for cracks or rounded internal splines. Replace any damaged knobs.
• Clean shafts: Wipe the exposed shafts with a dry cloth to remove grease and debris.
• Lubricate taps (technician): If gas taps are stiff, a technician can disassemble and regrease them with approved gas valve grease. Do not use household lubricants.
• Replace worn taps/switches: If shafts are bent or excessively worn, replace the gas tap or electric switch assembly.
