blower will not come on in heat mode

hello, my problem is when i turned on furnace this week i can hear the burner fire up, but the fan never comes on, and the high limit control cuts out the burner after a few minutes when the fan fails to come on in auto mode..... The fan does work in the A/C mode and in the fan on (manual) mode.... This past summer i had the reverse problem (fan not coming on in A/C mode) and the service man replaced the fan relay.... unit is a gas Rheem 64,000 BTU model # RGAA-0800 ..... any help would be greatly appreciated. Thanks Dan

I don't recall the model # you got.. but does it have a fan center? or a board in the blower area?

I would say the wire for heating part may not be hooked up if you have mulit speed blower..

To get by for now, turn the t-stat fan switch to "ON" to get heat if needed.
