If your system stops working, Gladiator is here for you, no matter the problem! In some cases, it may be able to be fixed with some quick troubleshooting, so before you call us, give these tips a try first.

Here’s What to Check First:


The status of your system’s power:

- Check fuses or circuit breakers to ensure they do not need to be present. - Keep in mind that if your home’s power is out or disconnected, your system may not work.

Your thermostat’s temperature and settings:

- Check your thermostat to make sure it has power. - Make sure it is on its “cool” or “heat” mode and not set to “off”. - Verify that it is set to the right setting and temperature.

Here’s what to do when you have no heat/poor heat:

- Make sure that your gas or electricity has not been turned off; if it is off, turning it back on should resolve the issue. - Check your thermostat to see if it is on and what the temperature is set at; if it is turned off or set incorrectly, turn it on and/or reset it. - Look at your home’s circuits and fuse box; if you have an open circuit breaker, turn it on; if you have a burned-out fuse, be sure to replace it as soon as possible. - Clear away any snow drifts that may be blocking your outdoor unit.

Here’s what to do when you have no cooling/poor cooling:

- Make sure no doors or windows are open in your home; if they are, be sure to close them right away to prevent any cool air from escaping through them. - Check your thermostat to see if it is on and what the temperature is set at; if it is turned off or set incorrectly, turn it on and/or reset it. - Look at your home’s circuits and fuse box. If you have an open circuit breaker, turn it on; if you have a burned-out fuse, be sure to replace it as soon as possible.

Here’s what to do when there is no air flow:

- Look at the area around your outdoor unit; if you see leaves, bushes, trees or property walls in close proximity, it may have caused your system to have a dirty coil and freeze up. Resolve this by making sure your outdoor unit has at least a 1-inch clearance around it. - Check the filters in your system; if they are dirty, they need to be cleaned or replaced. - Look to see if there is any air coming through your system’s vents; if you do not see any, your indoor blower may be malfunctioning, in which case you should call a Gladiator dealer right away.

Here’s what to do when you have stale or stuffy air:

- If you have an air cleaner/exchanger, make sure that it is on and that its filters are clean.

Here’s what to do if the air is overly dry or humid:

- For dry air, make sure your humidifier is turned on; for humid air, make sure your dehumidifier is turned on. - Make sure your humidifier’s damper or water valve is open; if it is not, refer to its manual to learn how to open or unclog it. - Check the setting of your humidifier/dehumidifier; adjust it according to the dryness/humidity in your home to improve comfort.

Here’s what to do when air vents are noisy:

- If you are hearing a high-pitched sound, it may mean there is a lack of return air; in this case, make sure the return and supply vents are open and are not blocked by anything, including furniture. - For rattling, humming, thumping or scraping sounds, the ductwork may be too small or weak, the filters may be clogged or there may be wear and tear on your system’s interior parts. In these cases, call a local Gladiator dealer ASAP!
