Table 12. Outdoor Control 7-Segment Display Alert Codes - Top Cap Switch
NOTE - System fault and lockout codes take precedence over system status codes (cooling, heating operating percentages
or defrost/dehumidification). Only the latest active fault or lockout codes are displayed (if present). If no fault or lockout codes
are active, then system status codes are displayed. Alert codes are also displayed on the iComfort Wi-Fi

thermostat.
Alert
Codes
Priority Alarm Description Possible Causes and Clearing Alarm
E 422 Moderate
Compressor top cap switch ex
ceeding thermal limit.
Check condenser fan motor, TXV, indoor unit blower motor, stuck reversing valve,
clogged refrigerant filter or undercharge. When error occurs with inverter slowdown
errors, check for system overcharge. Automatically clears when error is corrected.
E 442 Critical
The top cap switch has opened 5
times within one hour. As a result,
the outdoor unit is locked out
.
When compressor thermal protection sensor opens 5 times within 1 hour, outdoor stops
working. To clear, disconnect power to outdoor unit and restart.
Reactor Operations, Checkout and Status / Error Codes
OPERATION:
Reactor (Inductor or choke) is a passive twoterminal electrical component that stores energy in its magnetic field. Reactors
are one of the basic components used in electronics where current and voltage change with time, due to the ability of induct
ors to delay and reshape alternating currents.
CHECKOUT:
Main Power ON – Voltage IN reactor should be the same as the voltage OUT. With main power OFF and reactor disconnec
ted from system; resistance between leads should be the same (brown IN to brown OUT, blue IN to blue OUT).
STATUS CODES:
None
ERROR CODES:
None
Voltage “IN” same as Voltage “OUT”
