WARNING
4. Remove blower relay wire leads.
5. To check the relay contacts, connect an ohmmeter
R X 1 scale to relay terminals 3 and 4. No continuity
(open contacts) should be indicated. If continuity is
indicated, replace relay.
6. To check the relay coil, connect an ohmmeter R X 1
scale to relay terminals 1 and 5. A resistance reading
of approximately 7.3K ohms should be indicated. If a
zero or infinite ohms reading is indicated, replace
relay.
NOTE: Relay can also be removed and bench tested by
attaching a 120 VAC jumper cord to terminals 1
and 5. An audible click should be heard and
continuity indicated through contacts 3 and 4
when 120 VAC is applied to relay terminals 1
and 5.
Blower Relay

Fan Cutout Relay

The fan cutout relay is a single pole double throw (SPDT)
relay, which through its normally closed contacts, provide
a completed 120 VAC circuit path to the blower motor.
The coil contacts on the fan cutout relay are connected in
series with the four top burner spark switches.
Whenever any top burner/grill is turned to "LITE" the fan
cutout relay is energized opening the switch contacts and
the blower motor turns off. This action is necessary to
eliminate the possibility of blower air movement
interfering with ignition of top burner gas.
RS2310003 Rev. 0
To avoid possible electrical shock, personal injury, or death,
disconnect power and turn off gas supply before servicing,
unless testing requires it.
After top burner gas ignites and customer turns top
burner from "LITE" to any other setting the fan cutout coil
is de-energized allowing completed 120 VAC circuit path
to blower motor.
The fan cutout relay can be tested using an ohmmeter
set to the R X 1 scale and using the following test
procedure.
1. Turn off power to the range.
2. Remove storage drawer.
3. Remove cover box screws located at the left front
corner of the range. The fan cutout relay is mounted
to the cover box by screws and locknuts. The fan
cutout relay is identified by violet, white, black, and
gray wires attached to it.
4. Remove fan cutout relay wire leads.
5. Connect ohmmeter R X 1 scale to relay terminals 2
and 4. Continuity (closed contacts) should be
indicated. If continuity is not indicated, replace relay.
6. Connect the ohmmeter R X 1 scale to relay terminals
1 and 5. A resistance reading of approximately 7.3K
ohms should be indicated. If a zero or infinite ohms
reading is indicated, replace relay.
NOTE: Relay can also be removed and bench tested by
attaching a 120 VAC jumper cord to terminals 1
and 5. An audible click should be heard and
open circuit should be indicated through
contacts 2 and 4 when 120 VAC is applied to
relay coil terminals 1 and 5.
