Issue: The oven does not heat up, even though the screen says it is warming.
Step 1: If the oven is not heating, check to make sure the oven is not running demo firmware. If DEMO software is detected, load the current software to erase and replace the DEMO version.
Then run the heater test in the system setup. If the amperage readings shown on the display are within specifications, check for loose/intermittent wiring connections.
Step 2: If amperage readings shown on the display are NOT within specifications, check if the 30Amp fuse is blown. If it is blown, replace it. Then find the root cause of the blown fuse. If the fuse is not blown, continue to step 3.
Step 3: If the 30 Amp fuse is not blown, check for 208/240VAC present at the heater. If there is not 208/240VAC present at the heater, continue to step 4.
If there is 208/240VAC present, verify that the amperage reading displayed by the heater test in the system setup was correct using an Amp Clamp or Multimeter. If the amperage verified by the Amp Clamp or Multimeter matches the FAIL heater test, replace the heater element. If the amperage verified by the Amp Clamp or Multimeter is at approximately 8 Amps, but the heater test still shows FAIL, replace the I/O control board.
Step 4: If 208/240 voltage is not present at the heater, check that L2 power is leaving the I/O board. If L2 power is not present, replace the I/O control board. If L2 power leaving the I/O board is present, check for poor electrical connections.
Use only TurboChef approved cleaning chemicals. Using any other cleaning products may critically damage the oven components and void the warranty. You will need the following supplies:
- TurboChef Oven Cleaner (Part # 103180CS)
- TurboChef Oven Guard (Part # 103181CS)
- Nylon scrub pad
- Cleaning towel
- Disposable gloves
- Protective eyewear
- Dust mask (optional)
Step 1: Turn off both ovens by touching the Off icons on both the top oven screen and bottom oven screen. Then open the oven doors. Warning: The ovens operate at temperatures up to 550°F (285°F). Allow proper cooling to prevent injury. DO NOT clean the ovens until the ovens no longer display COOLING DOWN.
Step 2: Remove and clean the wire racks for both the top and bottom ovens. Wash, rinse, and sanitize the wire racks.
Warning: Make sure the oven interior is cool before removing the wire rack.
Step 3: Remove and clean the grease filters (top and bottom ovens). First, lift the grease filter by the handle and pull it forward. Then wash and gently rinse the grease filter using hot water. Warning: Do NOT use a water jet or scrub the grease filter.
Step 4: Clean the cook chambers (top and bottom ovens). To do so, use a food vacuum or damp towel to remove food particles from the cook chambers. Then spray Oven Cleaner onto the top, bottom, and sides of the oven interior. Caution! Do NOT spray Oven Cleaner into the holes on the back-oven walls or directly onto cook chamber lamps. Doing so may damage oven components and void the warranty.
To clean stubborn stains, spray Oven Cleaner and allow it to penetrate for 5 minutes. Clean the oven interiors using a nylon scrub pad. Wipe each cook chamber with a clean damp towel, and then a dry towel.
Step 5: Clean the top and bottom oven doors. Clean the metal portion of the oven doors with Oven Cleaner and a nylon scrub pad. Gently clean the glass windows with Oven Cleaner and a cleaning towel. Wipe the doors and windows with a clean, damp towel and then a dry towel. See the next step for important cautions.
CAUTION: Do NOT use abrasive cleaning supplies, such as steel wool, to clean the glass windows. Using abrasives may scratch the windows. When cleaning the glass windows, do NOT apply excessive force. Repairs will not be covered by warranty.
CAUTION: Do NOT scrub or attempt to clean the oven door gasket. Doing so may cause mis-alignment of the oven doors, and repairs will not be covered by warranty.
Step 6: Apply Oven Guard (top and bottom ovens). To do so, spray Oven Guard onto a clean towel. Wipe the interior walls and the inside of the oven doors. Caution: Do NOT spray Oven Guard into the holes on the back walls or directly onto the cook chamber lamps. Doing so may damage components, and will not be covered by warranty.
Step 7: Reinstall the grease filters and wire racks for the top and bottom ovens. There are notches on the rear right and left sides of the wire racks which fit over the pins on the sides of the cook chambers. Wire racks must be correctly installed to ensure proper oven operation.
Step 8: Clean the air filter, following this procedure:
- Remove the air filter from the back of the oven.
- Rinse the air filter with hot water, but do NOT scrub the filter.
- Allow the air filter to dry completely before re-installation.
Caution: Blocked air vents are NOT a warrantable claim. The filter must be cleaned regularly or replaced if damaged. During all oven operation, the filter must be in place.
Step 9: Clean the oven exterior. First, wipe the oven exterior with a clean, damp towel. Then wipe the oven exterior with a clean, dry towel.
Caution: Do NOT spray chemicals into any openings, such as the louvers on the side or rear panels. Doing so can damage oven components and void the warranty.
