Product Overview
QwikSwap™
The Low-Cost, Robust Alternative to Expensive Unreliable ECM Motors
It is impractical to have all the dierent variations of ECM motors on the truck, so a failed ECM blower motor typically 
means a trip to the parts house and a few hours wasted. 
Now you can have the solution on the truck and save money too.  
QwikSwap™ is a money saving solution that allows the replacement of a failed OEM ECM, X13® or SelecTech® Motor 
with a lower cost, more reliable, Permanent Split Capacitor (PSC) motor, along with a capacitor. 
There is a QwikSwap™ board for every type of ECM motor... 
and it is a solution you can have on the truck, and no custom programming is required. QwikSwap™ boards operate 
with any PSC motor up to 1 horsepower, either 120 or 240 VAC single phase. 
QwikSwap™ X1 (QT6101)
The basic QwikSwap™ X1 (QT6101) provides a single technician-selected motor speed when 
replacing a failed OEM Constant Torque ECM, X13® or SelecTech® motor. Installation is as easy 
as moving wires from the failed ECM motor to the QwikSwap™ X1 board, then connecting the 
replacement PSC motor’s common and power lead to the QwikSwap™ X1 board (along with a 
capacitor). 
QwikSwap™ X3 (QT6100)
QwikSwap™ X3 (QT6100) provides replacement of a failed OEM Constant Torque ECM, 
X13® or SelecTech® motor with Permanent Split Capacitor (PSC) motor while also ADDING 
performance improving variable blower air ow capability - like high end systems have. 
Installation is as simple as moving the wires from the failed ECM motor to the QwikSwap™ X3 
board, then connecting the replacement PSC motor’s common and three power leads (one for 
each speed) to the QwikSwap™ X3 board (along with a capacitor). 
QwikSwap™ V3 (QT6104)
QwikSwap™ V3 (QT6104) provides replacement of a failed OEM Variable Air Flow Rate ECM 
2.0. 2.3, 2.5 or 3.0 motor with a Permanent Split Capacitor (PSC) motor while maintaining 
variable blower air ow capability. As with any QwikSwap, installation simply requires 
moving wires from the failed ECM motor to the QwikSwap™ V3 board, then connecting the 
new PSC motor’s common and the three power leads (one for each speed) to the QwikSwap™ 
V3 board (along with a capacitor). 
Optional Humidity Sensor (QT6001) 
While QwikSwap™ X3, QwikSwap™ V3 and our QwikSEER+® WattSaver all provide variable blower air 
ow leading to improved humidity removal, if humidly remains an issue these control boards have a 
simple plug-in connection for this optional humidly sensor. When installed on the control board and 
the relative humidity in the return air is measured to be greater than 50%, the control board control logic 
changes from maximizing performance to maximizing moisture removal. Once the humidity drops to 
below 50%, the control board returns to optimizing performance.
