How to change: Proximity sensor - drop handle
Instructions on how to replace your drop handle proximity sensor.
If your roaster is not heating up (read here first) or there is a warning message on the screen (hatch open) when you move the drop handle to the downwards position, your proximity sensor could be broken.
HOW TO DETERMINE IF A PROXIMITY SENSOR IS BROKEN:
Remove the top plate so you can see the sensors.
Move the drop handle to see if a red light flashes on the sensor. If it does, it works.
If there is no red light, try to move the proximity sensor closer to the drop handle using a 12-millimeters spanner.
Check the connection on the PCB, ensuring that the cable hasn’t been pulled off or isn’t properly plugged in.
Check that the proximity sensors for the drop and charge handle haven’t been swapped.
If none of the above fixes it, your proximity sensor is broken. Buy a new one or contact support if your machine is still under warranty.
Where to buy Proximity Sensor
Your spare universal proximity sensor was sent along with your ROEST. If you don’t have a spare one, you need to place your order.

How to replace Proximity Sensor
TIME
5 - 10 minutes
TOOLS
2-millimeters hex keys (included in the package with ROEST sample roaster)
12-millimeters spanner
Instructions
Follow the steps below:
Remove the top plate using the 2-millimeters hex keys.
Using the 12-millimeter spanner, remove the proximity sensor in front of the drop handle. In order to remove the sensor from the machine you will have to undo the cable ties holding the proximity sensor cable in place.
Note: There is no correct order to how they must be tied together; the primary purpose is to keep the cables neatly in place and out of danger of getting damaged. You may notice we’ve tied some cables with loops before fastening them. This is useful when you have to change the PCB, making it possible to unfasten the components from the PCB without undoing the cable ties. You can use the photo above as a reference when tying the cables again. The pictures below show the trajectory of the cables from the drop and charge handle proximity sensors.
When the faulty proximity sensor has been removed, the new one must be installed. The proximity sensor comes with two nuts with a sawtooth pattern on one side. The direction of one of these nuts must be changed, so the sawtooth pattern faces the other way, as shown in the photos below.
When installing the new sensor, you have to make sure it doesn’t interrupt the trajectory of the charge handle, which can make the handle hard to move and destroy the new sensor.
Tie the new proximity sensor with cable ties, so it’s collected neatly, like in the photo below.
