To Next PageTo Next PageWhy is my Trane Furnace not heating enough, even though the blower runs constantly?
If your Trane Furnace isn't heating sufficiently and the blower operates continuously, consider these causes: * Dirty air filters: Clean or replace the filters. * Blocked supply or return registers: Ensure registers are open and free from obstructions.
What to do if my Trane XV95 Furnace blower is not working?
If your Trane Furnace blower isn't working, there are several potential causes: * The thermostat might be set incorrectly, so adjust it according to the operating instructions. * A fuse might be blown or a circuit breaker tripped; replace or reset the protective device. If the unit still does not operate call for servicer. * A component might be defective, call for servicer. * The burner may not be igniting; in this case, call for servicer. * The main gas line might be turned off; have the gas company check. * The blower door might be removed or ajar; close the door securely to restore power to the blower and gas valve. * There may be a lockout. To resolve this, turn the power off-on-off-on twice in 30 seconds.

This document is a user's information guide for Condensing Gas Furnaces with a Fan Assisted Combustion System, designed for Upflow/Horizontal and Downflow/Horizontal installations. It provides crucial information for safe operation, maintenance, and troubleshooting of the furnace.
The furnace is a heating appliance designed to provide warm air for residential or commercial spaces. It utilizes a fan-assisted combustion system, meaning a fan helps draw air into the combustion chamber and expel exhaust gases. The "condensing" aspect refers to its high efficiency, achieved by extracting additional heat from the exhaust gases by condensing water vapor within them. This process makes the furnace more energy-efficient than non-condensing models. The furnace operates with an automatic ignition system, employing a hot surface igniter to light the burners each time the comfort control (thermostat) signals a need for heat, eliminating the need for a continuously burning pilot flame. It is designed to circulate and filter air throughout the home, contributing to both heating and air quality.
The guide emphasizes safety as a primary concern for users. Before operating the furnace, users are instructed to read all safety information, particularly regarding fire, explosion, and carbon monoxide hazards. In case of a gas smell, specific steps are provided, including not attempting to light any appliance, avoiding electrical switches, not using a phone in the building, and immediately contacting the gas supplier or fire department. The manual warns against relying solely on smell to detect leaks and recommends U.L. recognized fuel gas and CO detectors.
To start the furnace, users must first ensure all safety information has been read. The comfort control (thermostat) should be set to its lowest setting, and all electric power to the furnace turned off. The furnace front panel is then removed to access the main gas valve. The external main gas shutoff valve and the toggle switch on the main gas valve inside the unit must be turned to the "OFF" position. A five-minute waiting period is required to allow any gas within the unit to escape. If LP gas is used, forced ventilation may be necessary. If no gas smell is detected after this period, the external main gas shutoff valve and the toggle switch are turned to the "ON" position. The front access panel is replaced, and the main electrical supply is turned on. Finally, the comfort control is set to the desired temperature. The combustion blower will start, followed by the igniter heating up. After approximately 15 seconds, the main gas valve will open, and the burners will ignite. If the main burners fail to ignite, users are instructed to turn off the main electrical supply or lower the comfort control setting and wait five minutes before repeating the process. If the furnace still does not light, all gas and electricity to the unit should be turned off, and a servicer or gas supplier contacted.
For complete shutdown, the external main gas shutoff valve and the toggle switch on the main gas valve inside the unit should be turned to the "OFF" position, and the electrical supply to the unit disconnected. The furnace is equipped with a manual resetting flame roll-out switch located near the burners. If flame roll-out occurs, this switch automatically trips, shutting off gas flow, and must be manually reset by pressing its red button.
The guide also provides general information about the furnace's operation. It highlights the importance of unobstructed combustion and ventilating airflow, advising against blocking air openings on or around the furnace. Users are cautioned not to store gasoline, combustible materials, or other flammable liquids or vapors near the furnace. The manual stresses that the combustion air for the furnace must be fresh and uncontaminated, warning against storing products like paints, varnishes, laundry bleaches, detergents, and household cleaners nearby, as their fumes can lead to heat exchanger and vent system deterioration. For horizontally vented furnaces, the vent and inlet terminals must be located at least 12 inches (18 inches in Canada) above the expected snow accumulation level.
Proper maintenance is crucial for the furnace's efficiency and longevity. The guide recommends cleaning the air filter once a month, with a visual inspection of the furnace also recommended monthly. During seasons of frequent use, the filter should be cleaned twice a month. Users are warned never to operate the unit for heating or cooling with filters removed, as this can lead to dust and dirt buildup, blocking airflow and forcing the unit to work harder, thus increasing energy consumption. Filters can be cleaned with a vacuum or household detergent, though users should check the aftermarket filter manufacturer's instructions if applicable.
To remove the filter, users must first disconnect power to the unit before removing the blower door to avoid electric shock. Filters may be located in the furnace blower compartment (bottom or side return air inlet) and secured with retaining brackets or in a filter rack. After cleaning, the filter must be securely replaced. When replacing filters, only high-velocity types of the same size as originally supplied should be used.
The manual also outlines "Regular Dealer Maintenance" steps, which should be performed annually by a qualified service professional before the heating season. These steps include:
The "Problem Solver" section provides a table of common problems, possible causes, and remedies, encouraging users to check these before calling for service. It also advises against "do-it-yourself" repairs on in-warranty units, as this could void the warranty. For cleaning the furnace's enamel finish, ordinary soap and water are recommended, with household detergent for stubborn grease spots, and a warning against lacquer thinner or other synthetic solvents.
