Welcome to Nestwell Property Managements 24/7 DIY Maintenance Center. Thank you for your question about your malfunctioning furnace.
There are many different variables that can cause a furnace to malfunction. These include weak or dying batteries, dirty filters, tripped breakers, gas disruptions by the gas company or city, or the furnace simply needs to be reset.
The following video will show you how to remove a Carrier thermostat faceplate, which should give you access to the battery compartment for a battery change:
In the event changing the batteries does not resolve the issue, please search for the previously listed terms in the DIY Maintenance Center for tutorials addressing those common issues.
Please be aware, in the event a vendor is required to tend to the issue, and it's found that your furnace is malfunctioning due to one of the above-listed variables, costs associated with a trip fee, and the repairs will be added to your tenant ledger.
If you need additional assistance, please log in to your Resident Portal and Request a Repair.
