XLT Pizza Oven Error Code Main Fan Low Amps: Fan Current Too Low
Main Fan Low Amps means the main fan's current stayed below the minimum level in the Main Fan Amp level table for ten seconds. The manual's step is a hard reset: unplug the oven for one minute, plug in and power on. If the error still exists, contact XLT.

What does XLT Main Fan Low Amps mean?
The main fan moves hot air through the oven chamber, and the controller watches how much current the fan motor draws. A running fan draws a current that falls within a range. The manual refers to a Main Fan Amp level table for the minimum. If the current stays below that minimum for ten seconds, the controller raises Main Fan Low Amps and flashes the FAN LED with the Alarm LED lit. A current that is too low may mean the motor is not turning properly, a connection has been lost, or the load is lighter than it should be. The manual does not list causes and does not print the table values in this entry. It gives the hard reset as its action and then says to contact XLT at 888-443-2751. A technician uses the table and a meter to judge the fan.
Affected models and control systems

Possible causes
Likely causes — what usually sits behind Main Fan Low Amps on this control. A technician confirms which one it is before any part is replaced.
- Fan motor wiring or connector loose, so the motor draws less current
- Fan motor weakened or worn
- Fan wheel loose on its shaft so the motor runs lightly loaded
- Current sensing circuit on the board reading low
Safe checks before calling for service
- Switch off the oven and let it cool.
- Do the manual's hard reset: unplug the oven for one minute, plug in and power on.
- Listen as the oven restarts for a normal fan sound and note any rattling or silence.
- If Main Fan Low Amps returns, contact XLT or a service company.
- Tell the technician what you heard from the fan and whether baking was uneven.
How a technician diagnoses Main Fan Low Amps
- Read the alarm and confirm the FAN LED pattern.
- Look up the minimum in the Main Fan Amp level table for this oven.
- Measure the fan motor current with a clamp meter during operation.
- Check the fan wheel, shaft and motor connections.
- Repair or replace the part that tests outside the table, then confirm the current is in range.
- Measuring fan current is live work on 208-240 V circuits.
- The fan sits inside a hot oven chamber, so it can be reached only when cool by a technician.
- Judging the readings needs the Main Fan Amp level table from the service manual.
How Main Fan Low Amps differs from similar codes
Main Fan High Amps watches the same fan for current above the maximum level, also for ten seconds. Its manual step begins with checking circuit breaker CB1.
