Swan air fryer not heating up
My Swan air fryer, just over a year old — the fan runs and the timer counts down but the food comes out cold or barely warm. Is this something I can fix myself or do I need an engineer?
Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Swan Retro SD90170 fan runs but does not heat
- The problem
- A Swan Retro SD90170 air fryer was reported to run its fan and count down normally, but food came out cold or only barely warm.
- Likely cause
- The discussion points to a fault in the heating circuit rather than the controls. The strongest suggested causes were a failed heating element, thermal cut-out/fuse, or a relay/control fault. Basket seating and temperature setting were also mentioned as basic checks.
- What fixed it
- The accepted advice was to check that the temperature was set high enough and the basket/drawer was fully seated, then run a brief high-temperature heat test to confirm whether any warm air was produced. If the fan blows but the air stays cold, the likely diagnosis is no power reaching the heater or a failed heater circuit. Internal dismantling was not recommended unless competent, and engineer repair or goodwill/warranty support from Swan was advised. No specific repair was confirmed.
- Checks to try
- Confirmed the fan runs
- Confirmed the timer counts down
- Check the temperature is set high enough
- Check the drawer/basket is fully seated
- Run empty for 3–5 minutes at a high temperature and check for warmth from the outlet air
- Note whether there is the usual hot-metal smell at startup
Safety: Isolate it from the mains before any internal inspection. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If the fan is running and the timer is counting down, but there’s little or no heat, the most likely faults are in the heating circuit rather than the controls. On a small countertop appliance like this, it can sometimes be something simple, but often it ends up being a failed heater, thermal cut-out, or relay/control fault.
1. Check the obvious first Make sure the temperature is actually being set high enough and that the drawer/basket is fully seated. Some air fryers have a safety switch that affects operation if the basket isn’t properly in place.
2. Try a simple heat test Run it empty for 3–5 minutes at a high temperature. Carefully check whether any warmth is coming from the outlet air. If the fan is blowing but the air stays cold, that strongly points to no power reaching the heating element or the element itself having failed.
3. Listen and smell If there’s no usual “hot metal” smell at startup and no heat at all, that again suggests the heater circuit is open. If it heats only slightly, a partial failure or control issue is possible.
4. Consider age and repair practicality Just over a year old is frustrating, but many air fryers are not especially economical to repair once out of guarantee. Internal faults commonly involve the element, thermal fuse/cut-out, thermostat/NTC, or control board.
5. Safety first Isolate it from the mains before inspecting anything internal. Because this is a mains appliance, I wouldn’t recommend dismantling it unless you are competent with electrical testing. A qualified engineer should handle any live testing or internal repair.
If it’s only just over a year old, also check whether Swan offer any goodwill or extended cover. WhitegoodsHelp AI

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
