I have an armstrong compak 10 gas and air. I can't get the blower to come on to blow the air through the vents. I replaced capacitor. The motor turns very freely by hand but just won't start.

Question edited for clarity and spelling of 'capacitor'.

This give details for the A30A Model

Or contact Armstrong Air direct and get the part from them

a Volvo (must we guess"?) 2010 xc 60???? no air jumper-ed too?
if yes controls bad.
but with all blend door motors dead, air will flow.
there is no blower blocking door/damper ( but Filter)?
no air flows? means what?
hot air?
cold air?
either?
or no ambient air flows. or all.above.?

most cars have at least 3 dampers
MODE (direction)
hot cold, manual control.
recir'/fresh.

case in point, if hot core and AC core are dead
and blower spins you still get ambient cab air flow or fresh.
cab filter clogged up.
I need more facts to know what tests to do.

Its drawing much to high amperage on startup. It may be dirty, unmantained, blocked with something, or a bad run capacitor. Likely, at this stage, it needs replacing. If its belt drive, be sure you have the proper slack and the bearings, if needed, are oiled and not faulty.

Hello, replace the capacitor as when there are storms sometimes they can cause a voltage spike and damage the capacitor. The capcitor will be a round or oval metal looking can next to the motor. When the blower motor runs slow the coil can start to freeze due to lack of airflow and this is why little air is coming out of the vents. If the capacitor does solve the problem then the motor will have to be replaced.

Hello, if no air is blowing thru the vents then it could be a bad blower motor, a bad run capacitor, or a bad control board. If the motor is getting voltage from the board and it will start by spinning the blower wheel by hand you capacitor is bad. If it does not the motor is shot, however if you do not get voltage from the board but there is voltage to the furnace then the board is bad.

have you checked your filter yet? the other thing to check is open the fan door and jumper the door switch,if there is one, and turn the furnace on. is the fan blowing air now?

2 things could be the problem 1 The blower motor capacitor has one out. This is a small oval or round piece that the wiring to the blower motor is attached if this is out the blower motor will not work. 2nd. the blower motor itself has burnt out. Replace the capacitor and the motor together should you have to change out the motor. Good luck hope this helps

you will have to replace the blower motor

1999 saturn the ac is no longer blowing air at all no heat no cold air you can hear it turn on but nothing. What do I need to look for?

Replaced capacitor and cleaned filter. Problem solved.
