Troubleshooting - Goodman AIR CONDITIONING CONDENSING UNIT 1 THRU 5 TON and GAS FIRED FURNACE Use And Care Instructions Manual

If your furnace is not operating or is performing improperly, take time to perform the following checks before requesting service. A couple
of simple checks may allow you to avoid a service call. If the following steps do not resolve the problem, contact a qualified servicer for
further troubleshooting and/or repairs. Do not attempt troubleshooting beyond that which is outlined below. Do not attempt repairs
yourself.
• Check the blower compartment sight glass. If LED is flashing, record the number of flashes seen in sequence, shutdown your unit as
outlined in the "Furnace Start-up" section and contact a qualified servicer for further troubleshooting and/or repairs. Refer to Installa-
tion Instructions for code identification. If not flashing, continue with checks.
• Check thermostat for proper operation. Verify that it is set on HEAT and that temperature (above room temperature) setting is
appropriate.
• Check fuse or circuit breaker in furnace electrical circuit. Replace as necessary.
• Check to see that the manual gas shut-off valve external to the furnace is in the ON position. If the valve is in the OFF position, turn
the gas ON following the start up procedures outlined in the "Furnace Start-up" section.
• Check for dirty filter(s). This in the most common cause of improper furnace operation. Replace or clean filters as necessary.
• Check for blocked return air or supply air grilles throughout you home. Grilles may be blocked by furniture, drapery, clothes, carpeting,
etc. Clear any blockage.
