NOTES:
1. AccuTemp-approved service providers should complete these PM tasks.
2. General PM items should be completed at the same time as biannual or annual PM items are
completed.
Igniter Assembly
The igniter probe ignites the main burners and depending on the kitchen cooking environment,
geographic location and cleaning solutions employed, the ventilation airflow can deposit airborne
material onto the probes, causing the burners to have difficulty lighting.
Required Material: nut-driver/wrench, Phillips screwdriver, stainless steel brush, Accutemp adaptor
part number. ATR-FT003 and a digital voltmeter able to read dc millivolts or dc uAmps
Tasks:
1. Remove the retaining screws and remove the probe assembly.
2. Brush all probes to remove foreign material.
3. Re-install the probe assembly and verify operation.
Flame Sense Assembly
The Flame Sense a flame on the main burners and depending on the kitchen cooking environment,
geographic location and cleaning solutions employed, the ventilation airflow can deposit airborne
material onto the probe causing irratic flame sense reading which can cause a ignition lock out.
Required Material: nut-driver/wrench, Phillips screwdriver, stainless steel brush, Accutemp adaptor
part number. ATR-FT003 and a digital voltmeter able to read dc millivolts..
Tasks:
1. Remove the retaining screws and remove the probe assembly.
2. Brush all probes to remove foreign material.
3. Re-install the probe assembly and verify operation.
4. Check millivolts by grounding black lead of adaptor to the chassis, then inserting the red lead into
socket of the connector containing the orange lead to the flame sensor. Reading should be above
30 millivolts.
Orifices and Burner Venturi
Burner orifices can collect dust and grease over time in any kitchen environment. If this material
blocks the orifices, the appliance will be less efficient and can cause intermittent operation or
complete shutdown.
Depending on the size of your appliance, there are a minimum of 2 and a maximum of 3 orifices that
require inspection and cleaning. Each burner will have an orifice.
Required Material: towel, soap and warm water, stiff wire smaller than the orifice nozzle or orifice drill
of the same size hole.
Tasks:
1. Dampen a towel with the soap and water solution and clean the orifice.
2. Take the stiff wire or orifice drill and insert it into the hole in the center of the orifice and run it back
and forth, making sure all foreign material is removed.
3. Clean the burner venturi opening so that it is free of any collected dust, grease and any other
foreign substances.
