Refrigerator

If your refrigerator conks out on a hot day and you have a cat or a dog, immediately check the coils for pet hair. Service pros find this problem on half of their refrigerator calls. The coils are the black tube-and-wire grid that cools the fluid in the compressor. A buildup of hair will cause the compressor to overheat and trigger the overload switch. On many fridges, you get to the coils by opening the grille at the bottom of the refrigerator. Then push a coil cleaning brush (sold at home centers) into the coils, pull it back and vacuum it clean.

If the coils are located on the back, pull out your fridge (it’s often on rollers) and brush them off. Bonus: The clean coils will cool more efficiently and save you money on your utility bill! Once the overload switch is tripped, you may have to wait a few hours for it to cool. It will reset itself and turn the refrigerator back on.

Gas Stove

If your stove burner won’t come on, the likely culprit is the spaghetti sauce that boiled over a few days ago. Use a toothbrush to clean off food spills from the igniter. On an electronic ignition stove, it’s a little ceramic nub located either on the stovetop or under the ceramic seal strike plate. Also make sure that the round ceramic seal strike plate is properly seated on the burner.

Electric Range

If your electric stove burner won’t heat, turn the burner off and pull it out from its socket. Then plug it in again and wiggle it around. If it feels loose, remove the burner again and gently bend the burner prongs slightly outward for a tighter connection. Easy does it. You could end up pushing the whole socket out of its bracket.

Standing Gas Pilot Range

To access the ignition system in an older-style standard gas range, pop the lid. It’s usually hinged on the back side. If the pilot flame is out, poke a needle into the pilot hole to clean out soot (be careful not to ream it wider). Brush off any debris and clean the tube that leads from the pilot to the burner. Then relight the pilot.

Oven Controls

Blame it on the technology. It so happens that if you set the “time cook” function, the oven, much like a programmed VCR, won’t turn on until the appointed time. You may have done this inadvertently, but if your digital display reads “hold,” “delay” or “time cook,” then the timer is engaged. You’ll have to clear it first by pushing the “off” button. On ovens with dials, be sure the knob is turned to “manual.”

Washer

When a washing machine cabinet rocks, it makes a horrible racket during the spin cycle. The solution is to simply readjust the legs. Screw the front legs up or down until the cabinet is level. When both legs are solid on the floor, tighten each leg’s locking nut. In most washers, to adjust the rear legs, gently tilt the machine forward and gently lower it down. The movement will self-adjust the rear legs.

Dryer

Our expert repairman responds to many “dryer-not- heating calls” only to find that the machine is set to “fluff air”—a non-heat setting. Avoid the embarrassment. Check the settings first. Another common cause of poor drying is a clogged lint filter. The filter may look clean, but it may actually be covered by a nearly invisible film caused by dryer sheets. This film reduces airflow and forces the thermostat to shut off the heat before your clothes are dry. Test your filter by pouring water into it. If the filter holds water, it’s past time to clean it. Pull out the filter and scrub it in hot water with a little laundry detergent and a stiff kitchen brush.

Also check the outside dryer vent for any lint that may have built up there. The louver door–style vent covers are notorious for lint buildup, which traps heat and turns the heat off in the dryer. Pull the cover completely off to get to these clogs.
