Kitchen Appliance Repair vs Replacement, from Dishwashers to Ovens

A simple framework for repair or replace

The failed part tells you most of what you need to know. Many common failures are inexpensive parts with straightforward labor: pumps, valves, switches, elements, igniters, fans and door gaskets. Failures in the structure of the appliance, such as a cracked tub, a rusted frame or a sealed refrigeration system, are harder to justify on an older unit.

Age and history come next. An appliance in the middle of its working life with a first problem is usually worth fixing. One near the end of its expected life, or one with a pattern of repairs, is often better replaced. Finally, ask whether you like it: if it is too small, too loud or the wrong size for a planned remodel, a repair may not be money well spent.

Dishwasher repair vs replacement

Most dishwasher problems are worth diagnosing before you shop for a new one. The symptom usually points to a small, fixable cause.

Problems that are usually repairable

• Poor cleaning: often a clogged filter, blocked spray arms or a detergent issue.
• Water left in the bottom: often a clogged filter, a kinked drain hose or a blocked disposal inlet.
• Will not start: often a door latch or control fault.
• Leaking at the door: often a worn gasket or a unit that is out of level.

When replacing the dishwasher is the better call

Replace it when the tub is cracked or rusted, when the door hinges and frame are failing on an older unit, or when a leak has damaged the floor or cabinet and the machine is near the end of its life anyway. Deal with any leak quickly, because standing water under a dishwasher damages subfloors and cabinet bases.

1. Clean the filterRemove and rinse the filter in the bottom of the tub.
2. Check the spray armsMake sure they spin freely and their holes are clear.
3. Inspect the drain hoseConfirm it is not kinked and has a high loop or air gap as local code requires.
4. Check a new disposalIf a disposal was just installed, confirm its dishwasher knockout plug was removed.
5. Check powerIf the unit is dead, check the breaker or the outlet under the sink.

Ovens, ranges and cooktops

Most oven and range failures are element, igniter or sensor problems, which are routine repairs. The cases for replacement are fewer and easier to spot.

Common repairable oven and range problems

• Electric oven will not heat: often a failed bake or broil element.
• Gas oven will not light: often a weak igniter.
• Uneven baking: a faulty temperature sensor or a door gasket that no longer seals.
• Cooktop burner will not light: often dirty or wet burner caps and igniters.

When an oven or cooktop should be replaced

Cracked glass cooktops, control boards for discontinued models and badly rusted oven cavities are where replacement starts to make more sense. Gas appliance repairs should be done by a qualified technician who tests for leaks afterward.

Refrigerator and freezer repair or replacement

A refrigerator that runs but does not cool well usually has a fixable problem: dirty condenser coils, a failed fan or a defrost fault. Ice makers and water dispensers fail often and are usually repairable too.

Sealed-system problems, such as a refrigerant leak or a failed compressor, are more serious and require an EPA Section 608-certified technician to handle refrigerant. On a newer refrigerator this work may be covered by the manufacturer warranty, so check the paperwork first. On an older unit, a sealed-system failure is the most common reason we see owners choose replacement. Our refrigerator troubleshooting guide covers the safe checks in more detail.

Energy, size and the remodel question

Efficiency can tip a close decision, but it is rarely a reason on its own to replace a working appliance. Newer refrigerators and dishwashers are often more efficient than the units they replace, and ENERGY STAR labels make comparison easier.

Size matters more if a remodel is coming. Dishwashers are usually a standard width, but refrigerators and ranges vary in width, depth and height. When new cabinets are planned, it is often smarter to repair the current appliance to keep it running and buy the replacement once the layout is set, so the cabinet openings match the new model.

Safe checks before a service call

A handful of simple checks resolve a surprising number of calls. Always unplug the appliance or turn off its breaker before touching anything inside, and do not remove panels on gas appliances.

• Check the breaker, GFCI outlets and whether the appliance is plugged in firmly.
• Look for a control lock or child lock that may be enabled.
• Clean filters: dishwasher filter, range hood grease filters, refrigerator water filter if it is old.
• Vacuum refrigerator condenser coils and make sure vents are not blocked.
• Read the error code in the owner's manual; many codes point straight to the cause.

When to stop and call a technician

Some symptoms are safety issues rather than inconveniences. Stop using the appliance and call a qualified technician if you notice any of the following.

• Smell of gas, or a burner that lights with a large, yellow or lifting flame.
• Burning smell, scorch marks, sparking or a breaker that trips repeatedly.
• Water leaking onto the floor from a dishwasher or refrigerator line.
• Refrigerator not cooling after the simple checks, since refrigerant work requires certification.
• Oven door that will not unlock after a self-clean cycle has finished and cooled.
