I have had a Whitfield Advantage 2 since 1989; do recommended clean/oil on regular basis and have had only one major repair (motherboard replacement about 9 years ago). However, recently when starting a fire and pushing on the start switch ---- only the house fan (convection) comes on immediately, the combustion blower does not come on for 3-4 minutes. To get the fire going, I have to leave the door slightly ajar to keep the fire burnining until the blower kicks in. Once the combustion blower comes on, I shut the door and the stove works as normal; also there are no shut-down issues. Thoughts on this problem would be appreciated. Also looking for a Whitfield service person in Victoria, BC area.
