7)Startup/Cool Down–MH and PH energize. There is a slight delay, then Comp, ConFM, and EvapFM energize and cabinet temperature or high-temperature alarm (Hi) appears on DM. Once DTh reaches 32°F (0°C), 4-hour Comp cumulative run timer starts.

a)Startup Diagnosis: Check that EvapFM energize. If not, confirm that the door(s) are closed and DS contacts are closed. Check EvapFM blades for binding. Next, check for 115VAC at DSR terminals 7 and 8. If 115VAC is not present, check DS continuity. If 115VAC is present, check DSR coil continuity and contact continuity between terminals 6 and 4. If coil or contacts are open, DSR is bad and must be replaced. Next, check for 115VAC between CM F6 and CM N5. If 115VAC is not present, check between CM L3 and CM N5. If 115VAC is present between CM L3 and CM N5 and not between CM F6 and CM N5, CM is defective and must be replaced. If 115VAC is present between CM F6 and CM N5, check EvapFM continuity.

b)Cool Down Diagnosis: Confirm that Comp and ConFM energize and cabinet temperature appears on DM. If not, confirm 115VAC between CM L3 and CM N5. If 115VAC is not present, confirm wiring connections are secure for both the power wire (CM L3) and the neutral wire (CM N5). If 115VAC is present and DM is off, check that the display cable between CM and DM is not disconnected; reconnect if loose. If DM is still off, CM or DM may be bad, so replace both. Next, check that Comp and ConFM are energized. If not, check for 115VAC between CM C1 and CM N5. If 115VAC is present between CM L3 and CM N5 (above) and not between CM C1 and CM N5, check CTh status. See "IV.C.Thermistor Check." If CTh ohm reading is in proper range, CM is bad and must be replaced. If 115VAC is present between CM C1 and CM N5, check for 115VAC on CR coil (terminals 5 and 6). If 115VAC is not present between CR 5 and CR 6, check continuity of HPS. If open, allow time for HPS to reset. If HPS does not reset, replace HPS and diagnose reason for HPS activation. See "IV.A.2.7)c) HPS Activation." If 115VAC is present between CR 5 and CR 6, and Comp and ConFM are not energized, check for 115VAC between CR terminal 4 and neutral and CR terminal 1 and neutral. If 115VAC is present between CR terminal 4 and neutral and not CR terminal 1 and neutral, CR is defective and must be replaced. If CR is good and Comp or ConFM are not energized, check for 115VAC at Comp terminals, Comp overload (internal on 1-section, external on 2-section), start components, and Comp and ConFM motor winding continuity.

If Comp and ConFM are energized and the cabinet does not cool down, check for a restriction in the refrigeration circuit, correct TXV operation, and correct refrigerant charge.
