Air fryer runs but does not heat; fan operates and timer counts down, food remains cold.

Safety first: Unplug and allow to cool before accessing internal parts.

• Confirm symptom: Run a short cycle and check if any warmth is felt at the exhaust. If completely cold, proceed with heater checks.
• Inspect heater wiring: Access the heater terminals and verify that all spade connectors are tight and not oxidized.
• Test heater and fuse: With power disconnected, measure continuity across the heating element and the inline thermal fuse. Replace any open components with Morphy Richards‑approved parts.
• Check relay operation: During a heating cycle, listen for a click from the main PCB. If no click and the heater circuit is good, the relay or triac may have failed; replace the main control PCB.
