Display shows P1 and grill runs at very low temperature with long pauses between pellet feeds

Note: On some Masterbuilt pellet controllers, P-settings (P1–P7) adjust the pellet feed timing and are not error codes.

• 1. Verify mode:
  • Check the user manual for your specific Masterbuilt model to confirm P1 is a smoke/low feed setting.
• 2. Adjust P-setting:
  • Use the +/- or dedicated P button to change from P1 to a higher P-number or to a standard temperature setting (e.g., 225°F, 275°F).
• 3. Observe operation:
  • If the grill now feeds pellets more frequently and temperature rises, the unit is functioning normally.
