How to Fix a Fermax Intercom That Is Not Charging
A Fermax video intercom system provides both security and convenience, but only when it's powered on. If you've noticed your monitor's screen is blank or it's showing a low battery warning but isn't charging when plugged in, it's crucial to address the problem. A non-charging unit can leave you unable to see visitors or open your door.
This guide will take you through a series of simple checks and troubleshooting steps to identify why your Fermax system isn't charging and how to resolve it.
## Common Symptoms of a Charging Failure
First, let's confirm the signs that point to a charging problem. You may be experiencing one of the following:
- No Charging Indicator: When you plug the charger in, the charging light or on-screen icon does not appear.
- Battery Level Doesn't Increase: The unit acknowledges the charger, but the battery percentage never goes up.
- The Monitor Won't Power On: The screen is completely black and unresponsive, even when connected to the charger.
- Loses Power Immediately When Unplugged: The monitor works when connected to the charger but powers off instantly if the cable is removed.
- A "Charging Error" Message: Some models may display a specific error message on the screen.
## Step-by-Step Troubleshooting Guide
Work through these solutions methodically, as the problem is often a simple one.
### 1. Check the Power Source and Cable Connections
Start with the most basic and common points of failure: the power source and the physical connections.
- Test the Wall Socket: Ensure the electrical outlet is working. Plug a lamp or another small appliance into the same socket to confirm it has power.
- Secure the Connections: Unplug the charging cable from both the power adapter and the Fermax monitor. Then, plug them back in firmly. Ensure the connector is pushed all the way into the charging port. A loose connection is a very common culprit.
- Inspect the Charging Cable: Carefully examine the entire length of the power cable for any signs of physical damage. Look for breaks, kinks, or fraying. Pay close attention to the connector tip to ensure it isn't bent or broken.
### 2. Test the Power Adapter
The issue may lie with the power adapter that plugs into the wall, rather than the cable or the monitor itself.
- Check for Lights: Does the power adapter have an indicator light? If so, is it lit?
- Try a Different Adapter: If you have another power adapter with the exact same voltage (V) and amperage (A) ratings, try using it to charge the Fermax monitor. Using an adapter with incorrect specifications can damage the unit, so check the label on the original Fermax adapter carefully.
### 3. Examine the Monitor's Charging Port
The physical charging port on the Fermax unit can become damaged or blocked.
- Look for Debris: Use a torch to look inside the charging port. Sometimes, dust, lint, or other small debris can get lodged inside and prevent the charger from making a proper connection. If you see anything, you can try to remove it carefully with a wooden toothpick or a can of compressed air. Do not use metal objects like paperclips, as you could cause a short circuit.
- Check for Damage: Does the port feel loose or wobbly when you insert the charging cable? If it does, the internal connection may be broken. This usually requires professional repair.
### 4. Consider the Battery's Health
If the monitor works perfectly when plugged in but won't hold a charge, the internal rechargeable battery may have reached the end of its operational life.
- Age of the Unit: How old is your Fermax system? Rechargeable batteries degrade over time and after many charge cycles. If the unit is several years old, battery failure is a strong possibility.
- Signs of Battery Failure: A key sign is a battery that drains extremely quickly or won't hold any charge at all.
If you suspect the battery has failed, it will need to be replaced. Depending on the model, this may be a user-replaceable part or may require a service call from a qualified technician. Contact your installer or Fermax support for guidance on obtaining and fitting a replacement battery.
