Remove condensate from line. Due to this infoemation of the board, voltage cannot be measured so ignitor must be ohmed. Remove heat exchanger from furnace cabinet. A digital readout meter must be used. In addition there is a 24 volt accessory terminal located on TB1. Keep tubing attached to pressure switches. Replace the threaded plug after measurements have been taken. This interference is caused by internal switching frequencies of the motor controller. Therefore, the prove switches must be bypassed after the combustion air inducer is activated.
If switch is closed or jumpered, the control will not initiate ignition at start up. Neutralize electrostatic charge by touching hand and all tools on an unpainted unit surface, such as the gas valve or blower deck, before performing any service procedure. CAUTION The exhaust vent pipe operates under positive pressure and must be completely sealed to prevent leakage of combustion products into the g61mpvv space.
Before attempting any service, make sure the indoor unit is causing the interference. In accordance to CSA International B installation codes, the minimum allowed distance between the combustion air intake inlet and the exhaust outlet of other appliances shall not be less than 12 inches mm.
By pressing ‘print’ button you will sevrice only current page. The longer the pulse, the faster the motor.
The difference should be in the range listed on the unit rating plate. Page 34 Dip Switch Settings operation during the cooling mode. In areas where piping penetrates joists or interior walls, hole must be large enough to allow clearance on all sides of pipe through center of hole using a hanger. The LED may flash rapidly or may display a single flash, depending upon the activity.
The unit is shipped from the factory with the dip switches positioned for medium low 2 speed indoor blower motor operation during the heating mode. Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at disconnect switch es.
Remove condensate from lines.
See tables 29 through If terminals are damaged replace control. High prove switch closed prior to activation of combustion air inducer. The motor uses permanently lubricated ball-type bearings. If you then smell gas, STOP! It’s a community-based project which helps to repair anything.
If the disconnect switch is bounced when the disconnect is closed, the disconnect contacts may become welded. S acts as a backup to primary limit S10 in the event of an indoor blower failure. The unit control indicates the desired cfm. Be careful when servicing unit to avoid sharp edges which may result in personal injury. Disconnect power before servicing. Combustion air inducer will not start with a Heating demand. When servicing controls, label all wires prior to disconnecting. The control also has two accessory terminals rated at 1 one amp each.
Exhaust and air intake pipes Check the exhaust and air intake pipes and all connections for tightness and to init sure there is no blockage. Remove seevice indoor blower to view this area through the blower opening. Resistance between any 2 contacts should be equal. If the limit is open, the furnace control energizes the supply air blower and closes the gas valve. The thermostat selection is made using a DIP switch which must be properly positioned for the particular application.
Heating cable installation kit is available from Lennox. If there is a simultaneous call for first and second stage heat, the unit will fire an first stage heat and switch to second stage heat after 30 seconds of operation. In attic or closet installations, vertical termination through the roof is preferred. After a 10 minute ujit period, the unit will switch to second stage heat. Y2 Call for humidity removal during 2nd stage thermostat demand Y2 Y2 Humidity level rises slightly 1 above setpoint.
The pH oiterature is a measurement of acidity and alkalinity. Note orientation of shield and limit if limit is replaced. Main voltage V not supplied to unit. Limits must close within 3 minutes or unit goes into 1 hour Watchguard.
