You should always include model number in requests. More info is better. In general, there is a setting for Heat and cold on cheaper thermostats. Mine is like that. It works for heating in winter and you must switch it to "cool" for summer. I assume you do have an AC unit for summer. Who wired it up? was it ever working? Did it get installed during winter? The wiring may be wrong, there are a lot of possible ways to wire. If you are not good at that (and why would you be here if you were?) better get a tech to check it out. In the old days, Edison might send out a tech for free to advise (not fix) if there is a possibility of short (dangerous).

The furnace may not be getting power. It could have been turned off when switched over from heating to cooling.

I tried to turn on my air coditioning today for the first time this year and my Totaline Themostat P474-1050 won't turn on. Worked fine during the winter and last summer.


the thermostat is powered by the unit or batteries if batteries they may be dead if the unit you need to check fuses outside at unit or reset breaker outside depending on age of installation

I can't find the summer switch on my furnace model FG6RA 072C-12A


there isn't a summer switch - the thermostat will switch the operation from heat/winter operation to cool/summer operation. I.E. "Cool" for Summer and "Heat" for Winter.

We have just had a Honeywell H46C humidity controller installed. The technician told us to set both the humidistat and digital thermostat at 65 degrees when we leave the FL condo for the summer. Is this...


If you are leaving for SUMMER, definitely do not need to set at 65, that would be tremendous waste of energy. Humidistat in summer should be off. I wonder if he thought you would be gone during winter.

Goodman with 2 thermostats, freezes in summer, no heat in winter


is the system zoned? if so maybe the zoning control board to the damper motor is wired improperly. when a system freezez its because of 1- restricted air flow across coil, (maybe dirty filter) or 2-low refrigerant charge. again could depend on how its zoned.
