If your GE microwave starts running or heating the moment you close the door — without pressing Start — you have a dangerous fault that needs immediate attention. In this video, the S&W Service and Repair team walks through exactly what causes this and how to diagnose it.

Why This Is Dangerous

A microwave that runs without being started means the magnetron is activating without user input. This can cause overheating, fire risk, and radiation exposure. Unplug the unit immediately and do not use it until the issue is repaired.

Common Causes

• Faulty door interlock switch — the most common culprit
• Shorted control board relay
• Stuck or damaged door latch assembly
• Wiring harness fault between door switches and control board

What the Repair Involves

Most GE microwave door-heating issues trace back to one of the three door interlock switches. These are inexpensive parts but require careful handling — capacitors in microwaves can hold a lethal charge even when unplugged. Always discharge the capacitor before working inside. If you’re not comfortable with this, call a professional. If your microwave runs but won’t heat at all, that’s a different set of parts — see over-the-range microwave not heating.

Best Appliance Repair Company in Denton, TX — What to Look For

When an appliance breaks down, you want it fixed fast — but you also want to make sure you’re hiring someone trustworthy and skilled. Here’s what to look for when choosing an appliance repair company in Denton, TX.

1. Local and Established

Choose a company that’s actually based in the Denton area and has been serving the community for a while. Local technicians know the area, can get to you faster, and have a reputation to protect.

2. Transparent Pricing

A good repair company tells you what the repair will cost before doing any work. Be cautious of companies that charge a large diagnostic fee and then add on high labor charges. You should get a clear estimate upfront.

3. Experienced with Your Brand

Major appliance brands — Whirlpool, LG, Samsung, GE, Maytag, Frigidaire — all have unique parts and repair procedures. Ask if the company has experience with your specific brand.

4. Reviews and References

Check Google reviews for honest feedback from past customers. Look for companies with consistent ratings and responses to reviews — that shows they care about their customers.

5. Fast Response Time

A broken refrigerator or washer can’t wait a week. Look for a company with clear appointment hours and quick scheduling in the Denton area.

5 Signs Your Refrigerator Needs Repair

Your refrigerator runs 24/7, so it’s easy to overlook small warning signs — until a bigger problem develops. Here are 5 signs that your fridge needs attention before it stops working altogether.

1. It’s Not Keeping Food Cold Enough

If your food is spoiling faster than normal or your drinks aren’t as cold as they should be, your refrigerator may have a failing thermostat, dirty condenser coils, or a refrigerant issue. Don’t wait on this one — food safety is at stake. If the freezer is still cold but the fridge side is warm, start with these freezer-cold, fridge-warm checks.

2. You Hear Unusual Noises

Some hum is normal. But loud clicking, buzzing, or rattling often signals a problem with the compressor, condenser fan, or evaporator fan motor. Catching this early can save you from a full compressor replacement.

3. There’s Water Pooling Inside or Under the Fridge

Pooling water usually means a clogged defrost drain or a failing water inlet valve. Left unaddressed, this can lead to floor damage and mold. Our guide to water dripping inside your fridge shows how to clear a clogged drain yourself.

4. The Ice Maker Has Stopped Working

A broken ice maker could be caused by a faulty water inlet valve, a frozen fill tube, or a control board issue. This is a very common repair and usually affordable to fix. These 10-minute ice maker checks will tell you whether it’s something simple.

5. Your Electric Bill Has Gone Up

A refrigerator working harder than it should — due to worn door seals, dirty coils, or a failing compressor — will use more electricity. If your utility bills are climbing, your fridge may be the culprit. If it seems to run all the time, see refrigerator running constantly.

How Much Does Appliance Repair Cost in Denton, TX?

One of the most common questions we get at S&W Service and Repair is: “How much will it cost to fix my appliance?” The answer depends on the appliance, the problem, and the parts needed — but we’ll break it down for you so you know what to expect.

Average Appliance Repair Costs in Denton, TX

Here’s a general range for common repairs in the North Texas area:

• Washer Repair: $100 – $350
• Dryer Repair: $80 – $250
• Refrigerator Repair: $150 – $400
• Dishwasher Repair: $100 – $300
• Oven / Range Repair: $100 – $350

These estimates include labor and parts for most common repairs. Complex issues like compressor replacement can cost more.

Is It Worth Repairing or Replacing?

A good rule of thumb: if the repair cost is less than 50% of the cost of a new appliance, repair is usually the better choice. A new washer can run $600–$1,200, so a $200 repair almost always makes sense.
