  If the blower does not start when powered up: * First, remove the cover. * Then, check for disconnected wire harnesses and reconnect them if necessary. * Next, check the fuses. Without AC power, measure the resistance across the F1 fuse with an ohmmeter. If the resistance is not between 0.0 to 0.5 ohms, the fuse is open, and the power supply board should be replaced. * If all fuses are closed, install a blower that is known to work properly and power up the unit. If the new blower works, replace the old blower. If the new blower still doesn't work, replace the control board. * Finally, replace the cover.
