Where is the reset button on a hottpoint side by side refrigerator.

Self Diagnostics

To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display can be illuminated by pressing an adjacent temperature adjustment button. When both displays are illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all 4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and freezer displays will indicate that the refrigerator is in Self Diagnostic mode.

To perform a self diagnostic test, locate the test in Table 2, Diagnostic Tests.

For temperature control panels with single-digit displays, the COLDER temperature adjustment button will increment the numbers up and the WARMER temperature adjustment button will increment the numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test. Press the HOLD button for 3 seconds to begin the test.

For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will increment the numbers down and the WARMER temperature adjustment button will increment the numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test code. Press any button other than a temperature adjust button to begin the test.

When testing has been completed, do one of the following things:

• Enter code 1 5 to completely reset the system.
• Enter code 1 6 to exit diagnostic mode. The temperature control panel is reset automatically.
• Unplug the refrigerator for at least 10 seconds. Test mode will terminate when the refrigerator is plugged back in.

Test mode will terminate automatically after 15 minutes of inactivity.

Code 24 and 25 (blend door actuator)are showing up

yes, IP must come out.

Actuator —Electronic Blend Door Removal
  1. Disconnect the battery ground cable. For additional information, refer to Section 414-01 .
  1. Remove the instrument panel. For additional information, refer to Section 501-12 .
  1. Disconnect the connector
But, you sure it's the blend door actuator?

Electronic Automatic Temperature Control Module Self-Test
  • The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns.
  • The EATC module self-test will detect concerns in the system control functions and will display hard diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4°-32°C (40-90°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false in-car temperature sensor DTCs will be displayed.
  • The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.
  • To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed.
  • If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given.
  • If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Improper Operation.
  • To exit self-test and retain all intermittent DTCs, push the blue (cooler) button. The control will exit self-test, retain all intermittent diagnostic trouble codes and then turn OFF (display blank).
  • To exit the self-test and clear all DTCs, press the DEFROST button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared.
  • Always exit the self-test before powering the system down (system turned OFF).
  • Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.
Connect a fused jumper wire between EATC module C228 pin 26, circuit 246 (VT) and EATC module C227 pin 2, circuit 54 (LG/YE). Connect a second fused jumper wire between EATC module C228 pin 13, circuit 245 (BN/LG) and EATC module C227 pin 3, circuit 57 (BK).
  • Does the actuator motor move in the clockwise direction?
