Range and cooktop guides carry a clearance diagram, and range clearance to cabinets is what it shows: the minimum space between the cooking surface and the cabinets above, and between the range and any wall or cabinet beside it. The diagram is there because heat and flames rise from the burners, and wood cabinets and walls nearby are combustible.
What the spec actually says
- •Amana AGR4230BA (30-inch gas range): The guide calls for a 30-inch minimum between the top of the cooking platform and the bottom of an uncovered wood or metal cabinet, or 24 inches when the cabinet bottom is covered with the specified flame-retardant millboard and sheet metal. It lists a 13-inch maximum depth for upper cabinets, 18 inches minimum from upper side cabinets to the countertop, and 2 inches minimum of countertop space to a side wall or other combustible material.
- •Amana AEP222VA (20-inch electric range): The overhead figures are the same, but the side figure is larger: 5 inches minimum of countertop space to a side wall or other combustible material. It adds that if cabinets above the surface units are used for storage, a range hood that projects at least 5 inches beyond the cabinet bottoms should be installed.
- •Whirlpool GCI3061X (30-inch induction cooktop): It repeats the 30-inch and 24-inch overhead rule and a 1-inch minimum to the nearest combustible surface on either side above the cooktop. Where a range hood or microwave hood sits above, it says to follow that product's installation instructions instead.
The overhead rule is consistent. Side clearance changes from model to model, so it's the number to check most carefully.
Why manufacturers require it
- •Rising heat: Cabinets directly over burners take the most heat. The 30-inch distance is meant to keep their surface from getting hot enough to scorch or ignite during normal cooking.
- •Protection allows less space: Covering the cabinet bottom with fire-resistant board and metal is why the guides allow 24 inches instead of 30.
- •Reaching over burners: Storage directly above the cooktop means reaching across heat. That's why the Amana guide calls for a hood projecting past the cabinets when they're used that way.
- •Side heat and flames: Burners near the range edge heat the wall or cabinet beside them. Larger burners and grates generally need more side room.
- •Cabinet depth: Limiting upper cabinets beside the range to 13 inches deep keeps them from overhanging the cooking area.
How to check your home against it
- Measure from the cooking surface (the grates or glass top) straight up to the underside of the cabinet or hood above.
- Check whether that cabinet bottom has any fire-resistant covering. If not, use the 30-inch figure.
- Measure from the edge of the range to the nearest side wall, tall cabinet or other combustible surface above countertop height.
- Measure the height from the countertop to the bottom of the upper cabinets on each side.
- Measure the depth of the upper cabinets beside the range.
- If a microwave or hood sits above, find its installation guide, which sets the clearance in its place.
What happens when it's ignored
- •Cabinet finishes scorch, blister or discolor above and beside the burners.
- •Hot cabinets and walls raise fire risk, especially during high-heat cooking.
- •Handles and knobs on nearby cabinets get hot.
- •A replacement range wider than the old one can quietly shrink the side clearance.
Over-the-range microwaves have their own mounting heights. See over-the-range microwave mounting height.
When it needs a licensed pro
- •Raising, removing or covering upper cabinets is work for a cabinet installer or contractor. Ask your building department about any permit.
- •Moving the range to gain clearance may need a new range outlet, which is a job for a licensed electrician, or a moved gas line, which needs a licensed gas fitter or plumber.
- •Adding a hood above the range may need a circuit and ductwork. See the hood's guide and use licensed trades.

Quick check: Measure from the grates to the cabinet above. Under 30 inches, with no protective covering, is out of spec.
Cabinets that get hot even at the right distance can mean a burner or element running hotter than it should. TrueFix Long Island can check it: call (631) 985-3690 or book through our range repair page.
