What We’re Seeing Most in Denton This Season – A DIY Troubleshooting Guide for July Heat

Your refrigerator’s running but the milk’s warm. The dishwasher finishes a cycle and the dishes come out wetter than when they went in. The dryer takes two cycles to dry a load of towels. If you live in Denton and any of that sounds familiar, you’re not alone. This time of year—Denton’s July average humidity is 70% – that’s why dryers struggle. The good news is some of the most common problems can be checked in ten minutes without any tools. The bad news is if you ignore the simple stuff, it can turn a fifty-dollar fix into a three-hundred-dollar repair.

Here’s what we’re seeing most often in Denton, Little Elm, Frisco, and Lewisville right now, and what you can safely check before you call.

1. Refrigerator Not Cooling – Check the Condenser Coils

If your fridge is running but the temperature inside is creeping up, the first thing to look at is the condenser coils. They’re usually underneath the fridge behind a kickplate, or on the back. Pull the fridge out, unplug it, and take a look. If those coils are caked with dust, pet hair, or lint, the fridge can’t dump heat. The compressor runs longer and harder, and eventually it trips the overload protector or burns out.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Dirty coils (cleaning) | $0 (brush/vacuum) | $80–$120 | N/A | | Bad start relay | $15–$30 | $120–$180 | N/A | | Failed compressor | N/A | N/A | $400–$700 | | Sealed system leak | N/A | N/A | $1,000+ |

What this tells you: Clean coils mean the fridge can breathe. Dirty coils mean the compressor is working overtime and will fail. The part involved is the condenser coil assembly and the compressor. If the coils are clean and the fridge still isn’t cold, the problem might be a bad start relay, a failed compressor, or a sealed system leak. That’s where you stop. Replacing a compressor costs $400–$700. A sealed system repair can run over a grand. Don’t mess with refrigerant lines unless you’re licensed.

Step-by-step for cleaning condenser coils: ![Image: Clear photo showing a refrigerator pulled out, with a brush and vacuum hose pointed at the coils underneath. Label: “1. Unplug fridge. 2. Remove kickplate. 3. Brush loose debris. 4. Vacuum coils. 5. Replace kickplate and plug back in.”]

2. Dishwasher Leaving Dishes Wet – Check the Rinse Aid and Drain Filter

Dishes that come out wet or with a white film usually mean the rinse aid is empty or the drain filter is clogged. Open the dishwasher, pull out the bottom rack, and look at the sump area. There’s a cylindrical filter you can unscrew or lift out. Rinse it under hot water. While you’re at it, check the rinse aid reservoir and fill it if it’s low.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Clogged filter (cleaning) | $0 | $80–$120 | N/A | | Empty rinse aid | $4–$8 | N/A | N/A | | Dead heating element | $30–$60 | $120–$180 | N/A | | Failed control board | N/A | N/A | $250–$400 |

What this tells you: A clean filter means water can drain properly. A full rinse aid tank helps water sheet off dishes instead of beading up. If both are fine and dishes are still wet, the heating element might be dead or the vent thermostat is stuck open. The parts involved are the heating element, the thermistor, and the vent assembly. Testing those requires a multimeter. If you’re not comfortable with electrical testing, call a tech. A misdiagnosed heating element replacement is a waste of money and time.

3. Dryer Taking Too Long – Clean the Lint Trap and Check the Vent

This one’s the most common in Denton July heat because humidity makes drying harder. But first, pull the lint trap out and scrub it with a brush and soapy water. The mesh can get a film of fabric softener residue that blocks airflow. Then disconnect the dryer vent from the back of the machine and check if air is moving freely. If the vent hose is crushed or full of lint, the dryer can’t exhaust moisture.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Dirty lint trap (cleaning) | $0 | $80–$120 | N/A | | Clogged vent (cleaning) | $10–$20 (brush kit) | $150–$250 | N/A | | Failed heating element | $40–$80 | $120–$180 | N/A | | Blower wheel broken | $25–$50 | $120–$180 | N/A | | Dryer fire from clogged vent | N/A | N/A | $500+ (plus damage) |

What this tells you: Good airflow means the dryer will dry in one cycle. Poor airflow means the dryer runs longer, wears out the heating element, and can start a fire. The parts involved are the lint filter housing, the vent ductwork, and the exhaust blower wheel. If the vent is clear and the dryer still takes forever, the heating element might be failing, the thermostats could be out of spec, or the blower wheel might be broken. Don’t keep running a dryer that’s slow—it’s a fire hazard. Stop and call S&W Service & Repair LLC to check it. A dryer fire from a clogged vent is not a repair you want to pay for.

4. Washer Not Spinning – Check the Lid or Door Switch

If your washer fills and drains but won’t spin, open and close the lid firmly. Listen for a click. If you don’t hear a click, the lid switch or door lock assembly is likely bad. On a top-loader, that switch tells the machine it’s safe to spin. On a front-loader, the door lock does the same job.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Bad lid switch | $15–$30 | $120–$180 | N/A | | Broken clutch | $50–$100 | $120–$180 | $300–$500 | | Failed motor | N/A | N/A | $400–$600 | | Worn drum bearings | N/A | N/A | $500+ |

What this tells you: No click means the control board never gets the signal to start the spin cycle. The part is a simple switch that costs $15–$30. Replacing it is straightforward if you can access it. But if the machine is making a grinding noise when you try to spin, the problem might be a broken clutch, a worn belt, or a failed motor. Don’t run a washer that’s grinding—you can damage the transmission or the drum bearings. That’s a $500 repair minimum. If you’re not sure, it’s smarter to book online and let a tech diagnose it.

5. Oven Not Heating – Check the Bake Element

If your oven isn’t getting hot, turn it on and look at the bake element at the bottom. Does it glow red? If not, it’s likely burned out. You can see a visual break or blister on the element. That’s a common failure on Whirlpool, GE, and Frigidaire ovens.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Burned-out bake element | $40–$80 | $120–$180 | N/A | | Bad oven thermostat | $20–$40 | $120–$180 | N/A | | Failed control board | N/A | N/A | $250–$400 |

What this tells you: A visibly broken element needs replacement. That’s a $40–$80 part and a 20-minute job. But if the element looks fine and still doesn’t heat, the problem could be the oven thermostat, the control board, or a bad relay. Testing those requires a multimeter and knowledge of the wiring diagram. If you replace the element and it still doesn’t work, you’ve wasted the part money and still have a broken oven. Call a professional from S&W Service & Repair LLC for that.

6. Ice Maker Not Making Ice – Check the Water Line and Filter

An ice maker that’s not producing ice usually means no water is reaching it. Pull the fridge out and check the water supply line. Is it kinked? Is the saddle valve open? If you have a water filter, replace it. A clogged filter reduces flow and the ice maker won’t fill.

Cost comparison: | Issue | DIY Part Cost | Service Call | Major Repair | |——-|————–|————–|————–| | Kinked line (fix) | $0 | $80–$120 | N/A | | Clogged water filter | $15–$30 | N/A | N/A | | Bad water inlet valve | $30–$60 | $120–$180 | N/A | | Frozen fill tube | N/A | $120–$180 | N/A |

What this tells you: A kinked line or closed valve is a free fix. A bad filter is a $20 fix. If water flows fine and the ice maker still doesn’t cycle, the problem could be a bad ice maker module, a failed water inlet valve, or a frozen fill tube. The water inlet valve is a common failure on Samsung and LG refrigerators. If you’re not comfortable working with water lines and electrical connections, don’t risk flooding your kitchen. A water leak from a bad valve can ruin flooring and drywall.

FAQ

Can I clean my own condenser coils? Yes, absolutely. Unplug the fridge, pull it out, and use a brush and vacuum to clean the coils. It’s a 10-minute job that costs nothing. Just don’t use a sharp tool that could puncture the coils.

Will a clogged vent cause a fire? Yes. Lint is highly flammable, and a clogged dryer vent traps heat. The U.S. Fire Administration says dryers cause over 2,900 home fires each year, most from lint buildup. If your dryer takes more than one cycle, check the vent immediately.

How often should I clean my dishwasher filter? Every 1–3 months, depending on how much you run it. If you see food particles on dishes or standing water in the bottom, it’s overdue. Rinse it under hot water—no soap needed.
