ECH TROUBLESHOOTING FLOW CHART
Step 4. Testing Voltage at ECH (Electronic Conrol Housing)
Using a volt/ohm meter set to read DC voltage, at the J1 connector, place one meter probe to pin 1 and one meter
probe to pin 2.
Do you have 30 to 34 VDC
at J1 from pin 1 to pin 2?
Yes
Replace ECH
No
Unplug wire harness from ECH to oven
controller. Now, reconnect wire harnes
to ECH and oven controller making sure
to get good connection.
No
Is display working now?
Yes, problem fixed
Replace wire harness
Step 3. Testing Voltage at Oven Controller
Using a volt/ohm meter set to read DC voltage, at the J11A connector, place one meter probe to pin 1 and one meter probe to pin2.
Do you have 30 to 34 VDC
at J11A from pin 1 to pin 2?
Yes
No
Remove wire harness from J11A to J1.
Measure continuity of all wires. Do you
have continuity on all wires?
Yes
No
Replace wire harness
Replace relay board.
Go to step 4
Step 2. Testing Voltage on Relay Board
Using a volt/ohm meter set to read AC voltage, place one meter probe to E1 (L1) and one meter probe to E2 (N).
Do you have 120 VAC
from E1 (L1) to E2 (N)?
Yes
No
Check voltage at unit terminal block at L1 and N.
Do you have 110 to120 VAC
from L1 to N?
Yes
Unit has loose or defective wire(s) between L1 of
terminal block and E1(L1) on relay board or N of
terminal block and E2 (N) on relay board.
Repair/Replace wires.
Go to step 3
No
Check for loose or defective wiring to unit
from terminal block to junction box/power
cord. May have to call an electrician
Step 1. Testing Wire Connections
Check wire connections at J4 connector on oven controller
to J1 connector of relay board, unplug both ends and reseat.
Check wire connections at J11A connector on oven controller
to J1 connector on ECH, unplug both ends and reseat.
Check wire connections at E1 (L1) and E2 (N) connector on
relay board, unplug both ends and reseat.
