SERVICING

Cooling Anticipator

The cooling anticipator is a small heater (resistor) in the ther-

mostat. During the "OFF" cycle it heats the bimetal element

helping the thermostat call for the next cooling cycle. This

prevents the room temperature from rising too high before

the system is restarted. A properly sized anticipator should

maintain room temperature within 1 1/2 to 2 degrees.

The anticipator is fixed in the subbase and is not to be

replaced. If the anticipator should fail for any reason, the

subbase must be changed.

S-4 CHECKING TRANSFORMER AND Control CIR-

CUIT

A step-down transformer 120 volt primary to 24 volt second-

ary, 40 VA (Heating and Cooling Models) supplies ample

capacity of power for either operation.

SOURCES MAY BE PRESENT.

AILURE TO DO SO MAY CAUSE

PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

1. Remove blower compartment door to gain access to

the thermostat low voltage wires located at the furnace

integrated control module.

2. Remove the thermostat low voltage wires at the furnace

integrated control module terminals.

With Power On (and Door Interlock Switch closed):

INE VOLTAGE NOW PRESENT

WARNING

3. Use a voltmeter, check voltage across terminals R and

C. Must read 24 VAC.

4. No voltage indicates faulty transformer, open fuse, bad

wiring, bad splice, or open door interlock switch.

5. Check transformer primary voltage at incoming line

voltage connections, fuse, splices, and blower door

interlock switch.

6. If line voltage is available to the primary side of trans-

former and not at secondary side, the transformer is

inoperative. Replace.

7. After completing check and/or replacement of trans-

former and check and/or repair of control circuit, rein-

stall blower compartment door.

8. Turn on electrical power and verify proper unit opera-

tion.

POWER BEFORE SERVICING.

WARNING

1. Remove blower compartment door to gain access to the

circulator blower motor and integrated ignition control.

2. Disconnect the motor wire leads from its connection point

at the integrated ignition control module and capacitor if

applicable.

3. Using a ohmmeter, test for continuity between each of

the motor leads.

4. Touch one probe of the ohmmeter to the motor frame

(ground) and the other probe in turn to each lead.

If the windings do not test continuous or a reading is obtained

to ground, replace the motor.
5. After completing check and/or replacement of circulator

blower motor or induced draft blower motor, reinstall

blower compartment door.

6. Turn on electrical power and verify proper unit operation.

CHECKING DUCT STATIC

The maximum and minimum allowable external static pres-

sures are found in the specification section. These tables

also show the amount of air being delivered at a given static

by a given motor speed or pulley adjustment.
The furnace motor cannot deliver proper air quantities (CFM)

against statics other than those listed.

Too great of an external static pressure will result in insuffi

cient air that can cause excessive temperature rise, resulting

in limit tripping, etc. Whereas not enough static may result

in motor overloading.
To determine proper air movement, proceed as follows:

1. With clean filters in the furnace, use a draft gauge (inclined

manometer) to measure the static pressure of the return

duct at the inlet of the furnace. (Negative Pressure)

2. Measure the static pressure of the supply duct. (Positive

Pressure)

3. Add the two (2) readings together for total external static

pressure.

NOTE:

Both readings may be taken simultaneously and read

directly on the manometer if so desired. If an air conditioner

coil or Electronic Air Cleaner is used in conjunction with the

furnace, the readings must also include theses components,

as shown in the following drawing.
4. Consult proper tables for the quantity of air.
