Why does my ChickenGuard repeatedly display the ‘door jam’ message?
If the ‘door jam’ message appears repeatedly, this means that your motor is having difficulty in lifting your door. This could be for one of two reasons; either your door is not sliding easily on the runners, or you have a tangled cord. Please check your runners, the weight of the door (waterlogged wooden doors weigh almost twice as much) and also have a look inside your unit to make sure your cord is spun correctly on the spindle. Please note that you will not be able to re-calibrate the door with the lid removed. Simply removing the batteries will not clear this message – you will need to clear the obstruction.
