Data Display Mode How to Enter: DV455* If you press the time button in service mode, the mode changes to data display mode. The failure of a component in this system will usually be indicated by one of three symptoms: 8 7 Will Not Dry Gas Model Poor Gas Ignition Technical_information-02835D-01_EN. Indd 8 2012-03-26 2:28:50 TROUBLE SHOOTING WARNING To avoid risk of electrical shock, personal injury or death; disconnect power to dryer before servicing, unless testing requires power. No Problem What To Do 8 The igniter does not glow If the igniter does not heat up, remove power and using an ohmmeter, check the following: • Open flame sensor • Open igniter • Shorted booster coil • Open wiring • Bad motor switch ( Neutral supply) • No power from control ( L1 supply) If the igniter heats up but the main burner flame is not ignited, remove power and using an ohmmeter, check the following: • Open secondary coil • Open holding coil • Open wire harness • Stuck flame sensor (Stuck closed) If a normal ignition takes place and after a short while the flame goes out, check for the following: • Radiant sensor contacts opening prematurely. €¢ Weak gas valve coil may open when stressed by higher Temps. thumping Check for loose tumbler baffle , rear tumbler roller(s) worn or misaligned , out-of-round tumbler or high weld seam on tumbler. Ticking Check for loose wire harness or object caught in blower wheel area. Scraping Check for front or rear bulkhead felt seal out of position or worn tumbler front bearings. 9 Igniter glows - No gas ignition 10 The gas is ignited but the flame goes out 11 Improper drying clothes wrinkled Rough texture long dry time 12 Noisy and/Or Vibration • • • 9 Technical_information-02835D-01_EN.
