Possible Causes
Faulty ambient NTC sensor on control board, Broken sensor lead, Poor solder joint on sensor, Moisture damage around sensor area
How to Fix / Troubleshooting
Safety first: Disconnect from mains before opening the control panel area.
Steps:
- Reset: Unplug for 10 minutes and retry. If E13 returns, proceed to hardware checks.
- Locate ambient sensor: On some Philips models, a small NTC sensor is mounted on or near the control PCB to measure ambient/control panel temperature. Identify this component (often a small bead or epoxy-coated sensor).
- Inspect and test: Check for cracked leads or corrosion. Measure resistance at room temperature and compare with service specs or with the main cavity sensor if similar type.
- Reflow or replace: If the sensor is PCB-mounted and has cracked solder joints, reflow with appropriate solder. If defective, replace the sensor or the entire control PCB.
Warning: Incorrect sensor replacement can affect safety margins; use only correct-value Philips parts.
