Continental Refrigerator Error Code Pr2: Evaporator Probe Error

Pr2 on a Continental refrigerator or freezer with the Evco-type control is an Evaporator Probe Error. The manual names probe Pb2 as the defective probe and says the reset is automatic. Have a technician check the probe, since it guides defrost.

Medium · inspection needed

Medium: defrost control is affected, which can lead to frost buildup over time.

What does Continental error code Pr2 mean?

Pr2 is listed as the Evaporator Probe Error in the alarm table for the Evco-type electronic control on Continental refrigerators and freezers. Probe Pb2 is the evaporator, or defrost, probe. It measures the temperature of the evaporator coil, and the control uses that reading to decide when a defrost has done its job. When the control cannot read Pb2, it shows Pr2. The table gives the code, the description and the reset, which is automatic, so the code should clear when the probe reads correctly. No causes or operator steps are given. What the control does without the Pb2 reading is not described either. Defrost might end on time instead of temperature, or run longer than needed, so a long-standing Pr2 can lead to frost buildup or warm cabinet air over time.

Affected models and control systems

Pr2 is listed for Continental refrigerators and freezers with the Evco-type electronic control and probes Pb1 to Pb3, in the Alarm Codes and Reset Types table printed on page 2 of the operations manual. Pb2 is the evaporator probe.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

  • Pr2 on the control display
  • Ice building up on the evaporator over several days
  • Cabinet temperature creeping up between defrosts

Possible causes

Likely causes — what usually sits behind error code Pr2 on this control. A technician confirms which one it is before any part is replaced.

  • Pb2 sensor connector loose at the evaporator
  • Probe cable damaged by ice or by a defrost heater
  • Sensor element failed from repeated freezing and thawing

Safe checks before calling for service

✓ What an operator can do
  1. Look for ice on the back wall of the cabinet or around the evaporator cover.
  2. Check the cabinet temperature with a thermometer.
  3. Do not chip ice or open the evaporator cover.
  4. Keep the door closed as much as possible to limit frost.
  5. Tell the technician that Pr2 is shown and how much frost you can see.

How a technician diagnoses error code Pr2

  1. Read the code and confirm it refers to Pb2, the evaporator probe.
  2. Check the probe at the evaporator for connection and damage.
  3. Measure the probe resistance against its chart.
  4. Observe a defrost cycle and see how it ends.
  5. Check the heater and defrost parameters.
  6. Replace the probe if it fails the test.
! Leave this to a technician
  • The evaporator compartment holds defrost heaters at line voltage.
  • Probe replacement requires opening the evaporator cover and handling a coil that can be damaged.
  • The defrost parameters are service settings.

How error code Pr2 differs from similar codes

Pr2 refers to the evaporator probe, whereas Pr1 refers to the return air regulation probe and Pr3 to the ambient probe.

Pr2Questions about Continental error code Pr2
Can I keep using the unit with Pr2?

Yes for a short time. Watch for frost and cabinet temperature, because defrost control is affected.

Will Pr2 clear by itself?

The manual lists the reset as automatic, so it clears when the probe is read correctly.

Does Pr2 mean the evaporator has failed?

No. It means the probe on the evaporator cannot be read.
