Sensor is shorted . Soft ware disengages heating pads . Acknowledge error by pressing the
ON/OFF button . If error persists, a qualifi ed service technician should test the sensor .
• Test the sensor . Detach the sensor from the warmer . Use an Ohm meter to measure
the resistance of the sensor . Check the sensor at 25°C (77°F) . If the reading is 10 KOhm
±1 .5 KOhm, replace the display . If the reading is ±2 KOhm, replace the sensor .
• Check the wires for integrity . Inspect the connections at the control and terminal
block to ensure proper and secure connections . If necessary, re-secure the faulty
connections .
• Call service if error persists .
