ESM initiates during periods of inactivity. Once CTh cools to setpoint, 20-min. ESM
timer starts. DS must remain engaged without activation (door open) for 20 min. after
CTh has achieved setpoint for ESM to initiate. Once 20-min. ESM timer terminates,
EvapFM operates on ESM cycle.
Diagnosis: Confirm 20-min. ESM timer terminates. Check that EvapFM cycles off with
Comp and operates 1 min. on and 5 min. off when Comp is de-energized. If not, replace
CB.
