– 15 –NOTE: Connections can be intermittent due to a corrosive buildup between theconnection to the terminals, or by being bent by the insertion of a probe, etc.ERC FAILURE CODESFAILURECODEStuck key pad or transistorfailure. May mean relay isturned on.If code cannot be cancelled, replacecontrol.Look for welded relay contacts. (Heatingelements on in off mode).Look for high resistance in the sensorcircuit due to high contact resistance(poor terminal crimp, deformed terminals,loose connection inside sensor tube) orintermittent solder joint.Electrical noise interference in the sensorcircuit (Ham radio, cordless phone etc.).Disconnect power to range.Disconnect sensor connector at control.Measure sensor resistance at controlconnector (take care not to damageterminals in block) - Should read1100 ohms at room ambient (approx. 72 F).Measure each sensor lead from connector block to ground. If shorted, look for pinched or cut wire insensor circuit.Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace.Check connector at sensor (remove sensor and carefully pull leads with connector into oven)If all above is ok replace control.Problem with door lock circuit suchas pinched wires between controland door lock switches.Check wiring and test operation of switches.Perform resistance check.Replace control.Door motor safety switch transistorfailureLoss of relay drive circuit Press Clear/Off and reprogram control.If -F5- code reappears, replace control.Check sensor circuit.Check lock circuit.If all above check OK the F5 code can be a result of a momentary loss of power (DONOT REPLACE CONTROL AND LOCK.) Check lock circuit.Could be result of contamination onterminals, pinched harness lead, or coldsolder joint on control.Open sensor (circuit) (over 2700ohms) Shorted sensor (circuit)(under 950 ohms)Control senses oven temperature above930 F with the door in the door locked mode.the door circuit in the unlock mode.Control senses oventemperature above 630 F withIndicates that oven is overtemperature in one of the followingmodes within either a cooking orclean mode of operation.-F2-Also seefanthermalswitches-F0--F1--F7--F3--F4--FC--FF--F5-MEANING CORRECTIONGEA00339
