Payne PF4MA air handler and X13 motor?
How do I test the X13 blower motor on my Payne PF4MA air handler? 
Our place in FLA has a Payne air handler and the blower won't run, causing the AC to ice up..
Have jumpered the thermostat and bypassed the discharge switch and the Blower still does not start up.. Is it possible to jumper the motor so that it will run?

HELP!! No Blower operation in Air Handler...temp inside the house is in the 80s
OK... I'm lost so here it goes 
I have a Payne PF4MNA037 air handler. it has an X13 240V 1/2hp motor and I'm using a Honeywell programable stat.
When we call for cooling, the coil cools, but no fan....so it freezes up.
The low voltage circuit has 28V (not 24v) and the primary power is 120 per leg.
There is a lead on the high voltage connector of the motor that goes to the low voltage transformer.... What is it's purpose and should it have a reading?
Is it safe to say that the motor has gone away?

Welcome to the forums.
I combined your two threads. It's best to keep all the posts in one thread to eliminate confusion.
The X-13 motor is not easily serviced. It is an electronically controlled motor.
Have you confirmed that you have 240vac inside the air handler ?
The following manufacturers video has excellent diagnostic steps for testing the motor.

Yes, the the Air Handler is receiving the required 240V .
I've seen that this furnace could have either the X13 or a PCM motor....
I'm strongly considering going to Grainger in Sarasota and purchasing the parts needed to install a PCM motor (motor, capacitor, relay, etc)..
Should I be concerned that my multimeter shows 28V from the secondary side??
I've seen many negative comments concerning these X13 motors and their reliability (especially here in FLA).I've seen that this furnace could have either the X13 or a PCM motor....

Any reason I should not do this?

Yes... PSC...
I went to Grainger, picked up a Dayton PSC 240V motor and Capacitor, and a DPST relay... Now I just need to remember how to wire it up.... assume both line feeds go to the relay, 28v Signal from the circuit board [blue] to one side of the low voltage side and brown to other.
Motor hooks to common, load sides of relay and Capacitor...
Since it's a 3 speed motor, but I only need 1, assume L1 goes to relay, as well ad the desired speed lead.... Am I correct?

If it's a two pole relay then L1 and the speed of your choice connect there. Be sure to insulate the extra motor leads.
