Symptoms

  • Darkened, bubbled, or peeling finish on cabinets next to the range
  • Countertop material discolored or warped near the cooktop
  • Heat felt strongly on nearby surfaces during cooking
  • Range installed close to combustible material without a heat shield

Likely causes

  • CommonInsufficient clearance between the range and combustible surfacesManufacturers specify minimum clearances that must be followed for safety.
  • PossibleMissing or damaged anti-scorch/heat shield if one is required for that installationSome installations require a shield if clearances are tight.
  • PossibleExcessive high-heat cooking directed toward one sideRegularly searing or using very high heat near an edge can accelerate damage.

What to do

  1. Stop using the burners closest to the damaged area until the clearance issue is assessed.
  2. Check your range's installation manual for the required minimum clearance to cabinets and countertops on each side.
  3. Measure your actual installation clearance and compare it to the manual's requirement.
  4. If clearance is insufficient, do not simply keep using it as-is, since this is a fire risk over time.
  5. Consider a heat-resistant shield product only if it's explicitly rated and recommended for this use, or better, address the underlying clearance.
  6. Have a kitchen contractor or appliance installer assess whether the range needs to be repositioned or a proper shield installed.

Tools and parts

  • Tape measure

When to call a pro

Have a kitchen contractor or appliance installer verify clearances and recommend a fix, which may involve repositioning the range or adding a proper heat shield.

Safety

Use caution

Insufficient clearance from a heat source is a fire risk over time; avoid using burners nearest the damage until it's assessed.
