Lamona Range Cooker Overheating After New Elements/Thermostat

[kkkbbb7788]

Hi, hoping someone can help me, have a Lamona HJA5110 range cooker, previously had a new element fitted on the RHS oven and it was overheating, so had a new thermostat fitted, still overheating, so never used it. So recently fitted new elements to both sides (LHS and RHS) with a new thermostat on the RHS (left hand one was fine), problem is now both ovens are overheating to approx 280 and 300 degrees. Any ideas? Advice? would be most welcome, thank you

check that the stats operate correctly (meter)set on VAC) and reassess your wiring.
