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.
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.

the oven center.
Once the bake temperature has been adjusted, broil temperatures are
automatically offset to the same degree.
Diagnostics Mode
Unplug range 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 20,000Ω per volt DC or greater.
■Check all connections before replacing components, looking for broken
or loose wires, failed terminals, or wires not pressed into connections 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.
General Procedure: Diagnostics Tests

également appliqué automatiquement aux températures de cuisson au gril.
Mode de diagnostic
Débrancher la cuisinière ou déconnecter la source de courant électrique avant
d’exécuter les contrôles suivants :
■La corrosion des pièces de connexion est une cause potentielle
d’anomalie de fonctionnement des organes de commande. Inspecter les
connexions et contrôler la continuité des circuits à l’aide d’un ohmmètre.
■Exécuter tous les tests ou contrôles à l’aide d’un voltmètre ou multimètre
d’une sensibilité de 20 000 Ω par volt CC ou plus.
■Contrôler toutes les connexions avant de remplacer des composants;
rechercher conducteurs coupés ou mal branchés, broches défectueuses
ou fils insuffisamment engagés dans les connexions. Un faisceau de
câblage endommagé doit être remplacé dans son intégralité. Ne pas
reconstituer un faisceau de câblage.
■Exécuter les mesures de résistance après avoir débranché le cordon
d’alimentation de la prise de courant et déconnecté les connecteurs
ou le faisceau de câblage.
Procédure générale : tests de diagnostic
1. Brancher la cuisinière ou reconnecter la source de courant électrique.
IMPORTANT : Dans le mode de test de diagnostic, le technicien peut
controler de nombreuses fonctions. Les deux aspects à surveiller portent
sur l’écran des anomalies (voir les étapes 14 à 15) et l’écran du mode de
test automatique (voir les étapes 16 à 20). Le test automatique est une
fonction d’autodiagnostic intégrée au module de commande du four, qui
fournit toutes les informations nécessaires au diagnostic et à la réparation
du four. Suivre les informations à l’écran pour effectuer l’intégralité du test
et identifier le code d’erreur et les composants à vérifier.
2. Accéder au mode de diagnostic en appuyant sur
CANCEL>CANCEL>START (annuler>annuler>mise en marche)
en moins de 5 secondes.
REMARQUE : Après chaque test, appuyer sur CANCEL (annuler) pour
revenir à l’horloge. Accéder au mode de diagnostic de nouveau en
appuyant sur CANCEL>CANCEL>START (annuler>annuler>mise en
marche) en moins de 5 secondes.
