Sensor is open. Software disengages heating pads. Acknowledge error by
pressing the standby button. If error persists, a qualified service technician
should test the sensor.
◾ Test the sensor. Disconnect the sensor from the warmer control PCB
and use an Ohm meter to measure the resistance of the sensor.
Sensor PR-37140 should measure 10 KOhm ± 1.5 KOhm at 25°C (77°F).
Sensor SN-33541 should measure 100 Ohm ± 10 Ohm at 25°C (77°F).
Replace sensor if measurement is outside of tolerance.
◾ Check the wires for integrity. Check for proper and secure connections
at the control and terminal block. If necessary, re-secure the faulty
connections.
◾ Contact service if error persists.
E-30 Under
temperature
The blanket cavity temperature is lower than the set temperature for 90
minutes or longer.
◾ Make sure the door is closed.
◾ If the cavity is overloaded, redistribute the inventory. Do not exceed the
height of the insert.
◾ Test the sensor. Disconnect the sensor from the warmer control PCB
and use an Ohm meter to measure the resistance of the sensor.
Sensor PR-37140 should measure 10 KOhm ± 1.5 KOhm at 25°C (77°F).
Sensor SN-33541 should measure 100 Ohm ± 10 Ohm at 25°C (77°F).
Replace sensor if measurement is outside of tolerance.
*E-31 Cavity sensor ◾ The sensor reading is above the temperature set-point. Blanket warmer
triggers at 15° over set-point. Fluid warmer triggers at 5° over set-point.
◾ The difference between the room temperature and the fluid set-point
temperature must be greater than 11°C (20°F).
◾ Contact service if error persists.

Heater pad over-temp error.
◾ Software disengages heating pads.
◾ Acknowledge error by pressing the standby button.
◾ Allow the warmer to cool.
◾ Contact service if the error persists.
*E-33 Cavity sensor ◾ Sensor reading is above maximum allowable temperature set-point and
over temp value. Blanket warmers trigger at 82°C (180°F). Fluid warmers
trigger at 71°C (160°F).
◾ Contact service if error persists.
*E-50 Analog to Digital
Converter Error
◾ Remove inventory, discard if necessary, and allow the warmer to cool
down.
◾ If error persists after cool down and reset, the control assembly should
be replaced by a qualified service technician. Contact service.
