3.4 Condenser

The condenser is a steel tube serpentine with copper alloy fins, which removes heat from
hot, high pressure vapor from the compressor. The common trouble is lack of air flow
from either a restricted intake or exhaust opening in the front of the unit. Lint, dust, hair,
and dirt build-up needs to be removed from the condenser periodically to allow the unit
to perform properly.
It is possible that the condenser might need replaced because of an un-repairable leak or a
restriction that cannot be flushed out. System high pressures and temperatures will verify
if this is the case.
Removal
1. Disconnect power, water line, and drain line. If a drain pump is used, it will need to
be disconnected and removed.
2. Remove the access panel and rear panel (see figure 3.3).
3. Remove the grille by removing the two screws and disconnecting the three wires to
the rocker switch. Be sure to mark where these wires go for re-assembly.
4. Remove the drain valve.
