Temperature Control Diagnostic Codes
309574L 11
E02: High hose current
1. Check tap connection at transformer, see operation
manual.
2. Check hose connections for electrical short, page
43.
3. Move to lower hose length on transformer.
4. Replace temperature control board, page 38.
E03: No hose current
E03 (lollipops)
Do all of the steps in order with out skipping any steps. If
you don’t you may misdiagnose the failure.
1. Check hose connectors for broken electrical con-
nection, page 43.
2. With the main power off, and the hose plugged in,
test the continuity of the heated hose through the
Reactor unit. Pull connector J13 off of the tempera-
ture control board and remove the red wire from the
transformer hose length tap. Perform a continuity
measurement between pin 6 of the J13 wire har-
ness (not the board) and the wire removed from the
transformer tap. You should have continuity. If no
continuity exists, trace the wires until you find the
problem. See F
IG. 1.
Check transformer. If transformer has “lollipops”
located in front, refer to E03 (lollipops). If the
transformer does not include the “lollipops,” refer
to E03 (no lollipops).
