7 Appliance Errors You Can Diagnose in 60 Seconds
Posted by Rodney · 2026-05-05
Not every appliance problem needs a $130 service call. Some of the most common errors I get called for are 60-second fixes that homeowners can handle themselves. Here are seven — what to check, how to fix, and when to actually call.
1. Washer won't drain — try this first
Before calling about a tub full of water, check the pump filter. On most front-load washers (Samsung, LG, Whirlpool, Bosch), there's a small access panel at the bottom front. Behind it is a screw-out filter that catches coins, hair clips, and lint. Pull a shallow pan, twist out the filter, clear it, twist back in. Half the 'won't drain' calls I get are this. Call me if: filter is clean and water still won't drain — that's the actual pump or hose.

2. Dryer takes forever — clean this one thing
It's almost never the dryer. Pull the dryer out, disconnect the transition hose, and look at the lint inside the wall vent. If it's packed, that's your problem. Long Island homes need vent service every 1-2 years. Call me if: the wall vent is clean and the dryer still takes forever — then it's a heating element, igniter, or thermostat.

3. Dishwasher won't drain — run this first
Run the disposal. Most dishwashers drain through the disposal connection. If you've recently put a lot of food down and the disposal hasn't been run, the dishwasher drain backs up. Also: clean the filter at the bottom of the wash tub (every dishwasher has one). Call me if: disposal is clear, filter is clean, and water still pools — drain pump time.

4. Refrigerator running constantly
Pull the unit out. Look at the condenser coils underneath or behind. If they look like a wool sweater, vacuum them. Dusty coils can't release heat, so the compressor never cycles off. Wait 24 hours after cleaning. Call me if: coils were clean (or this didn't help) — could be a defrost issue, fan motor, or door seal letting warm air in.

5. Oven temperature feels off
Buy a $10 oven thermometer. Put it in the center, set the oven to 350°F, wait 20 minutes. If it reads more than 25°F off, the oven thermistor is drifting. That's a $30 part — but not a DIY swap. Call me if: the temperature is consistently off — sensor replacement and recalibration is fast.

6. Stove burner won't ignite (gas)
Take a paperclip and gently clear the spark hole on the burner head. Then brush the burner cap clean of any spilled food. Try again. Spilled grease and food clog the spark gap surprisingly often. Call me if: still no spark — could be the spark module or the igniter switch.

7. Microwave runs but doesn't heat
Test by heating a cup of water for 60 seconds. Cold? It's real. Don't open the microwave. The high-voltage capacitor inside can hold lethal charge even when unplugged. This is a call-a-pro one — door switch, magnetron, or HV diode. None of these are DIY territory.

Saving a service call when you can is good for both of us. I'd rather you fix the easy stuff yourself and call me for the things that actually need a tech. If any of these don't work after you try them, call me — most of those repairs wrap in a single visit anyway.
