S-16B ECM/ICM Motors

ECM/ICM Features

Many of the Amana

®

 brand high efficiency package units in-

corporate the GE

©

 ICM or variable speed blower motors for

greater efficiency. ECM/ICM motors vary the motor RPMs to
provide a set volume of air over a wide range of conditions.

ECM/ICM Control Connections

Control functions (G, Y1, Y2) May be Active at less than 1/2
control voltage. (i.e. 12 volts). Relay contacts on control func-
tions must reliably switch low currents (less than 5 MA).
Some thermostats (with triac switches) and Solid State Re-
lays may allow enough "leakage" current to Turn on "G".
Thermostats that "steal" power thru "Y" or other functions
are not compatible.

The ECM control interface can be as simple as a direct con-
nection to the thermostat. For example: R to G will cause fan
to come on at "fan-only" CFM. R to G to Y will cause fan to
come on at cooling speed. The ECM/ICM control requires a
common connection from the transformer (transformer com-
mon to C1, C2 on control). In typical applications C1 and C2
will be tied together. Additional features can be utilized with
an interface control board (speed tap board), these features
include; 2 Cool CFMs, 2 Dehumidification CFMs,  2 Heat
CFMs, emergency heat CFM, separate Fan-Only CFM, and
feed back information (CFM demand).

Testing ECM/ICM Motors

ECM/ICMs connect directly to the Line. 

DO NOT

 Insert

Contactors in Series with the ECM/ICM Motor AC line. Con-
trol is powered continuously to Insure reliable start-up. Plug
is polarized, verify and reverify correct connector orientation
before applying power. 

DO NOT

 force plug into motor and

make sure power is off before inserting power connector. 

DO

NOT 

apply voltage to terminals 1 or 2.

WARNING

L

INE VOLTAGE NOW PRESENT.

Check for line voltage on terminals 4 and 5. Verify terminal 3
is ground. Terminals 1 and 2 should be connected 

only 

if

motor is operating on 120 Volts.

Control connections

Do not  apply 24 volts to terminals "Out +" or "Out-".

Make sure connector is fully seated.

Make Sure Pins are Fully Seated in Connector Housing.

Verify C1 and C2 are connected to transformer common.

Verify "R" is connected to transformer hot.

After verifying above connections, motor can be tested by
applying 24 volts to control pins. Example: R to G will cause
fan to come on at "Fan-Only" CFM. R to G to Y will cause fan
to come on at cooling speed.

If motor does not respond as noted, ECM control unit is bad
and should be replaced.
