I changed batteries but still no display n thermostat don't light up. pro1iag model T701. What to do?


Verify that you in fact replaced the batteries with GOOD batteries. If you can separate the thermostat from the sub-base, hold it in your hand and replace the batteries again. If the display does not come up at that point, it is time to change the thermostat.

Thermostat is working, but display is blank


My thermostat used to go blank when heating. It was caused by the overheat protector inside the heater. That switch cuts the power to the heater and the thermostat. The heater could also be burned out. If it's a 24Volt system, the power supply could be bad.

The display went blank on my honeywell t8600c thermostat. when the batteries were changed, the display shows the time and -AC. Nothing else functions


I believe this thermostat will display -ac if it loses power from the furnace or air handler. Your thermostat will operate on low voltage(same as your door bell) and constantly powers your thermostat. I would check your furnace breaker, and fuses to see if there is power to the equipment

Thermostat is bad. Relace the thermostat. I suggest having a professional replace the thermostat as there are many ways to install incorrectly and lead to expensive service call to repair.

We have a White-Rodgers 90 series thermostat that started beeping last night. We have had it for about 4 years. Does it have a battery? I couldn't find anything about that in the manual.


Susan, the "90" series of thermostats covers a couple of different thermostats made by White-Rodgers. Here's how to find your model number. With that info, I can check the manual specific to your thermostat.

In the mean time, check the display for the word BATTERY or BAT. (Flashing) on the display. Battery flashing or blinking on the digital display indicates low batteries. If the batteries have recently been changed and the thermostat continues to indicate low batteries, use a pencil eraser to polish each of the battery contacts inside the back of the thermostat. Do not bend them up and down when polishing or you might break them. When complete, they should all be as shiny as a mirror. This will assure proper battery back-up, allow the backlight to work correctly and remove the flashing battery symbol from the screen. Battery (Solid) on Display The battery symbol (not blinking) indicates a loss of power (24 volts) from the heating and cooling equipment to the thermostat. Normally the heating and cooling do not operate when the battery indicator is on. If the battery indicator is on, check the fuses or breakers, make sure the furnace is switched on, and verify the blower compartment door is closed properly. The battery display is designed to indicate the thermostat is running on batteries, so replacing batteries has no effect on the indicator. See No Heat/No Cool for more information. Note: Some heat only systems (zoned systems) disconnect power from the thermostat during a normal heating cycle and display the battery symbol. Millivolt heating systems always indicate battery because they do not supply 24 volts to the thermostat.

A beep often is provided as audible feedback when keys are depressed on many thermostats. You should check to make sure that no key is stuck in the "in" position or is otherwise activated.
