7. INSPECTION AND REPAIR
♦
This Heater is provided with the self-diagnosis circuit by which if the Heater operation becomes inoperable (unburnable) for some reason, inspection and repair can given according to “Error (E)”
Display.

Explanation 1.
The failure of the Circulation Fan Motor may sometimes be caused by the
broken wire of the Circulation Fan Motor or by the defectively assembled
Fan which touches the neighboring part. The latter case can be corrected
by refastening the screws. The output voltage failure with the Main Circuit
Board may also cause the Circulation Fan Motor trouble. Use the tester to
check to see if the terminal of Circulation Fan Motor has an output of
AC 230 V (for High and Med-High combustion).(The above test is to be
given with the Circulation Fan Motor terminal as being connected.)

If the High Limit Switch is caused with trouble, check to see if the contact
point has the proper electric conductance. The contact point is normally
ON-contact. If the curtain plugs the Air Filter, the High Limit Switch is
actuated to stop the operation of the Heater. This stop operation is not a
miss-operation, but a normal operation. If this happens, carefully check the
installing place of the Heater.
(Check the place where the trouble
occurred.) The trouble of an erroneous operation may be caused by the
direct sunbeams to which the Heater is subjected from the rear side of the
Heater or by the portional heat rise in the High Limit Switch due to the
exterior air blow which is caused near its outgoing and incoming place. If a
trouble that corresponds to this case occurs, change the installing position
of the Heater.
