The short answer
Why a Flooded Microwave Is Dangerous
Water and electricity do not mix. If a microwave has been submerged in floodwater, water can seep into the magnetron, the high-voltage capacitor, and the control panel. Turning it on could cause a short circuit, an electrical shock, or even a fire.
Floodwater is not clean. It carries mud, chemicals, and bacteria. These contaminants can corrode internal parts and leave residues that are unsafe to heat food near. Even if the microwave looks dry, hidden moisture and debris can remain inside.
What to Do After a Flood
First, make sure the microwave is unplugged. If the plug is wet or the outlet was submerged, do not touch it. Turn off the power at the breaker if needed. Let the microwave air out in a dry, ventilated space for several days.
Do not test it by running it empty or heating a cup of water. Testing can cause arcing or a surge that damages the appliance further. Instead, contact a qualified appliance repair professional to inspect the unit. They can check for corrosion, damaged wiring, and other hidden issues.
- Unplug the microwave before any inspection
- Keep it away from children and pets
- Do not use it until a pro says it is safe
- If the cord is frayed or the casing is cracked, replace the unit
- If the microwave was submerged in sewage or chemical water, replace it
Drying Alone Is Not Enough
Some homeowners think that letting a microwave dry out for a week makes it safe. Drying helps, but it does not remove corrosion or debris that can cause problems later. Salt or minerals in floodwater can remain and conduct electricity even when the surface feels dry.
A professional can test the internal components with proper equipment. They can identify damage that is not visible from the outside. If the microwave is old or the floodwater was heavily contaminated, the repair cost may exceed the value of the appliance. In that case, buying a new one is the practical choice.
When to Replace Instead of Repair
If the microwave was submerged for more than a few minutes, the risk of internal damage is high. The cost to repair a flooded microwave can often be more than half the price of a new one. Plus, a repaired unit may never work reliably.
If the microwave has a glass turntable, a metal interior, or a digital display, floodwater can cause long-term issues. Even if it turns on after drying, the magnetron may be weakened, leading to uneven heating or early failure. For safety and peace of mind, replacement is usually the right route.
Preventing Future Flood Damage
Flooding can happen from heavy rain, a burst pipe, or an overflowing appliance. To protect your kitchen, elevate small appliances like microwaves off the floor. Store them on a counter or shelf that is above likely flood levels.
If you live in Orem, keep a list of local water damage pros handy. They can help with flood cleanup and structural drying after any water event. Acting quickly to remove standing water and dry out your home reduces the chance of mold and further damage.
Also, check your insurance policy to understand what is covered for flood damage to appliances. Policies vary, and your insurer decides what is covered. Knowing this ahead of time helps you make informed decisions.
- Keep appliances off the floor in flood-prone areas
- Install a water alarm near your kitchen or laundry room
- Know how to turn off your home's main water valve
- After any flood, dry the area thoroughly within 48 hours
- Have a professional inspect electrical systems after a flood

Can a flooded microwave be repaired?
Sometimes, but only after a professional inspection. The pro will check for corrosion, damaged wiring, and moisture inside the magnetron and control panel. If the floodwater was clean and the microwave dried quickly, repair might be possible. If the water was dirty or the unit is old, replacement is safer.
How long should a microwave dry before using it?
Drying time depends on how wet it got and the humidity in your home. In a dry, warm room, a week may be enough for surface moisture. But drying does not remove internal corrosion. Always have a professional test it before you plug it in, even after a long drying period.
Is it safe to use a microwave that only got a little wet?
No, not without inspection. Even a small amount of water can cause a short circuit. Water can seep into the touchpad, vents, or seams. If you see any moisture inside the glass or on the metal surfaces, do not use it. Get a professional opinion first.
