Rangemaster 110 dual Fuel Dual Fuel Range Cooker

We have been very disappointed with the Rangemaster which we purchased through Northern Ireland Electricity showrooms. We have had problems, albeit under warranty, since we purchased the unit about four years ago. In quick succession the fan went; then the fan oven door came loose and was an absolute pain to fix; then the runners on the drawer; then the fan oven heating element; then the element of the regular oven. Overall, not impressed at all. We are currently trying to source the heating element of the fan oven and not having much joy in NI.
