Replace it.
• During ignition the dryer will draw X amps. With the burner ON, the dryer will draw X amps. If the dryer is
drawing amperages above this, then the house wiring, fuse box or circuit breaker is suspected to be at
fault.
• Igniter harness loose and shorted to base.

When the dryer is operated on a heat setting, the igniter should be energized and burner shall fire within
45 seconds at 120 VAC. The failure of a component in this system will usually be indicated by one of three
symptoms:
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.
• Weak Hi-Limit
• Poor venting
• Bad drum seals
