o Always perform initial inspections including visual, current and airflow (Figure A) tests before servicing a heater.
o Check the AC cord, wires and plugs, for cut, pinched or exposed wires, secure connection and proper location.
o NEVER touch the glass portion of a heating element. Always visually inspect the elements and perform a resistance test.
o The heating elements are wired in 3 parallel circuits and are suggested to be replaced in pairs for this reason. (FIGURE B)

o Visually inspect the heating elements and their connections. Turn on the heater and look for non-working elements.
o Test the resistance of the heating elements. They should measure 14 +/- 5% (13.3 – 14.7).
o Replace a heating element if the glass or the ceramic ends are cracked or broken, overly discolored, if the quartz element
appears to be damaged or if the wire insulation is excessively whitened (more than 1/4”) near the bulb. (FIGURE F)
o Test the unit with a new thermostat sensor.
o Remove the leads to the high limit switch and perform a continuity test. If any resistance, replace.
o Test the unit with a new circuit board.

(FIGURE A) AIRFLOW TESTING (FIGURE B) BULB PAIRING – Bulbs are wired in 3 series of pairs
and should be replaced in pairs accordingly.
(Figure C) LARGE WIRING BLOCK
(FIGURE D) FRONT CIRCUIT BOARD
(FIGURE E) SMALL WIRING BLOCK
(FIGURE F) EXAMPLE HEATING ELEMENT
This is a heating element that may have failed. Notice the whitening of the wires
where they enter the ceramic end caps. It is recommended that bulbs with this extent
(approximately 1/4”) of whitening (and the corresponding paired bulb) should be
replaced even if they test okay as their life expectancy could be diminished.
