USER MANUAL JJW2427LM JENN-AIR

Electrical Shock Hazard

Only authorized technicians should perform diagnostic voltage measurements.

After performing voltage measurements, disconnect power before servicing.

Failure to follow these instructions can result in death or electrical shock.

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

Voltage Measurement Safety Information

When performing live voltage measurements, you must do the following:

Verify the controls are in the off position so that the appliance does not start when energized.
- Allow enough space to perform the voltage measurements without obstructions.
- Keep other people a safe distance away from the appliance to prevent potential injury.
Always use the proper testing equipment.
After voltage measurements, always disconnect power before servicing.

FOR SERVICE TECHNICIAN'S USE ONLY

IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance

-OR

Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

Before removing the part from its package, touch the antistatic bag to a green ground connection point or unpainted metal in the appliance.
- Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
■ When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

Diagnostics

Unplug oven or disconnect power before performing the following checks:

A potential cause of a control not functioning is corrosion on connections. Observe connections and check for continuity with an ohmmeter.
All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 per volt DC or greater.
Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough. Damaged harness must be entirely replaced. Do not rework a harness.
Resistance checks must be made with power cord unplugged from outlet and with wiring harness or connectors disconnected.
If the oven does not heat, there may be a problem with connections to the power supply. Check the connection to L2.

IMPORTANT: Do not replace the control if there is no evidence of any failure.

To Enter Diagnostics Mode:

Before proceeding with any corrective action, perform the following steps to enter the Diagnostics mode:

1. Enter Diagnostics mode by pressing the same 3 keystads 3 times in a row. Single Ovens: Press KITCHEN TIMER>TOOLS> SELF CLEAN (repeat 2 more times).
