Oven does not heat at all in any mode; display and light work but cavity remains cold.

Safety first: Isolate the oven from mains power before any disassembly.

• Confirm timer settings: Ensure the Salter timer is set to manual or continuous mode; a timer set to "auto" can prevent heating.
• Check thermal cut‑out: Access the overheat thermostat/thermal fuse on top of the cavity. Reset if it has a button; otherwise test for continuity and replace if open.
• Inspect selector switch: On models with a rotary function selector, check for burnt contacts or loose wiring. If the switch feels loose or does not click positively, replace it.
• Check supply to elements: With power off, inspect wiring from the control PCB or selector to each element for burns or disconnections. Repair any damaged wiring with high‑temperature cable.
• Replace control PCB: If all wiring, cut‑outs, and selector are good but no elements receive power, the main control PCB is likely faulty and should be replaced.

Warning: Do not bypass safety thermostats to restore heating; this is unsafe.
