Few weeks ago i noticed a burn smell coming from the heater on the house, it smell like the first time you turn the heater on in the winter and it burns the dust or hair trapt on the coils during summer. and i noticed a lower flow of air coming from the unit. it does blow a little heat but not suficient to heat the house. i did check the filters and i did not change them for 4 months (ups....) i was thinking that the coils on the heater are chocked with dust and dirt, (since i did not change the filters sooner and because of the burn smell) however this morning i turn the unit off and turn on the fan only, and it did not came on. i check the brackers and all of them are O.K. (2 for the A/C and 2 for the Heater. out side the house by the unit, and 1 in the box where all the brackers fro the house are) at this point i am thinking that a fan may be the problem, but i am not sure. do you guys have any ideas on what i may do. thank you.
Blower moter not comeing on. motor bench test ok. were is time relay located? please help.

THE BURNING SMELL IS NORMAL. BEFORE HEATING SEASON OPEN ALL DOORS AND TURN THE HEAT UP AND LET RUN TILL ALL DUST IS BURNT OFF. IF BLOWER IS NOT COMMING ON NOW. THERE ARE 2 TIME DELAY RELAYS, AND ANOTHER RELAY FOR "FAN ONLY OPERATION". ALWAYS MAKE SURE THEY ARE NOT THE PROBLEM BEFORE REPLACING AN EXPENSIVE MOTOR.
