Imagine going golfing, coming back home, and the doorbell malfunctions as it starts raining.
It’s a concern when a doorbell begins to ring on its own.
You are going to wonder what’s going on and whether or not the ring is a sign the doorbell is damaged.
This is going to happen if your doorbell rings when it rains.
If a doorbell rings when it rains, the most likely cause is water seeping through the casing causing the wiring to short. This will cause the doorbell to ring. A secondary reason can include a loose doorbell, which rings when the property shakes due to thunder or heavy wind.
In any situation, you will want to take a look at how stable the doorbell is and if the casing is permeable.
This means water can go through the case due to potential gaps along the sides. If that is the case, you will want to tighten or change the casing as soon as you can. Otherwise, the doorbell will always ring when it rains or gets windy.
This article will look at the reasons a doorbell rings when it rains.

Reasons Doorbell Rings When It Rains
1. Rainwater Seeping Into The Doorbell
When it rains, the water is going to be everywhere.
This can create a situation where your doorbell is left exposed to inclement weather. It’s essential to make sure you pay attention to the weather because that will often let you know what the root cause of the problem is.
If a doorbell rings on its own in the rain, the water is likely getting through the casing.
There is a casing that runs around the doorbell to protect the wiring. In most cases, this will do a good job of keeping the wiring safe.
However, if it starts to show signs of aging, the rainwater can get into the doorbell causing it to short.
When it shorts, the doorbell will malfunction and possibly ring a few times.
There is nothing to worry about except it’s time to change the casing. It is likely too damaged and has to be changed as soon as possible.

2. Thunder Shaking The Casing
When a doorbell rings in the rain, you will also want to take a look at how much impact the casing is taking.
For example, you might have a situation where thunder is shaking the casing.
If thunder is shaking the casing, this might be the reason for the doorbell ringing. It will be similar to someone pressing against the doorbell while standing outside.
When the casing is loose, even a little bit of movement due to thunder is enough to cause the doorbell to ring.
3. Heavy Winds Shaking The Casing
Just like the thunder, it could be something as simple as heavy winds in the area.
If it is a windy day, you will notice parts of the property rattle. This can include a situation where the winds continue to shake to the point the doorbell rings.
When the casing is loose, it will shake due to the wind.
You will want to look at the casing and make sure it is tightened. It should sit flush against the frame or it will continue to shake as time goes on.
Being detailed is key when it comes to a situation such as this.

4. Loosened Wiring
It is also important to think about the wiring in the doorbell.
Is the wiring starting to loosen?
This can create a scenario where the doorbell rings on its own all the time. This includes whether or not it rains.
You might notice it rings when it rains but that might be due to additional movement because of the wind.
Open up the casing, inspect the wiring, and see whether or not one of those wires is loose. If they are, tightening them should take care of the issue.
This is not always going to be the main reason for a doorbell ringing in the rain but it is one cause to think about once you go through the other reasons.
Final Thoughts
This is why your doorbell rings when it rains.
If a doorbell rings when it rains, the main reason is a loose casing or water seeping in causing the doorbell to short and ring. To fix the issue, tighten the casing, inspect the wiring, and make sure everything is tight.
If you tighten the casing, this will prevent rainwater from getting through and it will also ensure thunder or wind doesn’t impact the doorbell.
If you don’t do this, the casing is going to remain loose and will eventually cause the doorbell to break down.
Change the casing as soon as possible and/or tighten it to ensure this stops.
