Make sure every oven door is fully closed and sits flush. If it comes back, it needs a visit. ### Can hanging a towel on my AGA eR7 cause error 139? Yes. AGA warns that anything draped over the top left door can block the control vent and let the panel overheat. ### What else sets off 139 on an AGA eR7 besides a door? AGA also names missing plugs in the thermocouple conduits and poor insulation. Those are for a technician to check once doors and vents are ruled out. --- **[Read on the site: AGA eR7 oven showing error 139 | OvenRepair.center](https://ovenrepair.center/error-codes/aga-139/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
