Pinpoint Tests

DIAGNOSTIC TEST A: DOOR IS DIFFICULT TO OPEN OR CLOSE FROM ANY DOOR HANDLE

Normal Operation and Fault Symptoms

The door latch can be operated from inside or outside by the door handle. When operated, the door latch releases and allows the door to open. If the door latch or door hinges have insufficient lubrication, or if the latch or door is misaligned, this causes additional effort to open or close the door.

Possible Sources

Door Alignment
Door Hinges
Striker Adjustment
