Aube thermostats, known for their energy-efficient designs by Honeywell, sometimes present the frustrating issue of aube thermostat not turning on. Understanding that electrical wiring plays a crucial role in their operation is important because faulty connections are often to blame. Moreover, the heating system itself needs to be in proper working order, as a malfunctioning boiler or furnace can prevent the thermostat from activating. If you’re facing the problem of aube thermostat not turning on, this article will guide you through some quick fixes to get your home back to a comfortable temperature.

Aube Thermostat Not Turning On? Quick Fixes Revealed!
When your Aube thermostat refuses to power on, it can be frustrating, especially during extreme temperatures. Before calling a technician, there are several straightforward troubleshooting steps you can take. This guide provides practical solutions to help you diagnose and potentially fix the problem yourself. We’ll primarily focus on addressing the common issue: your "aube thermostat not turning on."
1. Basic Power Checks: Is the Thermostat Actually Getting Power?
The first, and often simplest, step is to verify that the thermostat is actually receiving power. Many issues are resolved at this stage.
1.1 Checking the Circuit Breaker
- Locate Your Electrical Panel: Find the main electrical panel in your home. If you’re unsure where it is, consult your home’s documentation or ask someone familiar with your house.
- Identify the Thermostat’s Breaker: Look for the breaker that controls the thermostat circuit. It might be labeled "Thermostat," "Heating System," or something similar. If unsure, you may have to systematically switch each breaker off and then on again until you find the correct one – just be careful.
- Inspect for Tripped Breakers: A tripped breaker will usually be in a "middle" position between "On" and "Off."
- Reset the Breaker: Flip the breaker fully to the "Off" position, then back to the "On" position.
- Observe: After resetting, wait a few minutes and check if the thermostat powers on.
1.2 Examining the Thermostat Wiring
- Safety First: Turn off the power to the thermostat at the circuit breaker before touching any wiring.
- Remove the Thermostat Cover: Carefully detach the thermostat cover. Usually, it snaps off or is held in place by small screws.
- Inspect the Wires: Check the wires connected to the thermostat terminals. Look for:
- Loose connections.
- Corrosion or damage.
- Broken wires.
- Tighten Loose Connections: If you find any loose wires, gently tighten the screws holding them in place. Ensure the wires are securely fastened.
- Repair or Replace Damaged Wires: If any wires are corroded or damaged, you may need to replace them. This might require professional assistance. If you are not comfortable working with electrical wiring, consult a qualified electrician.
- Reassemble and Test: Carefully reattach the thermostat cover and restore power at the circuit breaker. Check if the thermostat powers on.
2. Thermostat Settings and Programming Errors
Sometimes, the issue isn’t a lack of power, but an incorrect setting or programming error that makes it appear as though the Aube thermostat is not turning on.
2.1 Reviewing the Program Schedule
- Access the Thermostat Menu: Consult your Aube thermostat’s manual to learn how to access the program settings.
- Check the Current Day and Time: Ensure the thermostat is set to the correct day and time.
- Examine the Heating Schedule: Review the programmed heating schedule. It’s possible the thermostat is set to a lower temperature or is programmed to be "off" during the current time.
- Override the Program: Try manually overriding the program by increasing the target temperature. See if the heating system activates.
2.2 Checking the Thermostat Mode
- Heating vs. Cooling: Some Aube thermostats have separate heating and cooling modes. Ensure the thermostat is set to the correct mode for the current season.
- "Off" Mode: Make sure the thermostat isn’t accidentally set to the "Off" mode.
3. Battery Issues (For Battery-Powered Models)
While many Aube thermostats are hardwired, some models rely on batteries for power or backup.
3.1 Checking Battery Status
- Low Battery Indicator: Look for a low battery icon on the thermostat display.
- Replacing the Batteries: If the battery is low, replace it with the correct type and size. Ensure the polarity is correct (+/-).
4. Thermostat Lockout or Error Codes
Some thermostats have a lockout feature or display error codes when a problem is detected.
4.1 Investigating Lockout Mode
- Consult the Manual: Check your Aube thermostat manual for instructions on disabling the lockout mode. This may require entering a code or pressing a specific sequence of buttons.
4.2 Deciphering Error Codes
- Identify the Code: Note any error codes displayed on the thermostat screen.
- Look Up the Code: Consult your thermostat’s manual for a list of error codes and their meanings. The manual will usually provide troubleshooting steps for each code.
5. Compatibility and Wiring Issues (Advanced)
This section requires a better understanding of your heating system. If you are not comfortable, contact a professional electrician or HVAC technician.
5.1 Thermostat Compatibility
| Feature | Description |
|---|---|
| Voltage Requirements | Ensure the thermostat’s voltage requirements match your heating system (e.g., 24V). |
| System Type | Confirm the thermostat is compatible with your type of heating system (e.g., baseboard, furnace). |
5.2 Incorrect Wiring
- Verify Wiring Diagram: Compare the wiring connections on the thermostat to the wiring diagram in the manual.
- Correct Miswiring: If the wiring is incorrect, carefully rewire according to the diagram. Remember to turn off the power at the breaker before making any wiring changes.
If after going through these steps, your "aube thermostat not turning on" problem persists, it might indicate a more serious issue with the thermostat itself or your heating system. In this case, consulting a qualified HVAC technician is the best course of action.
FAQs: Troubleshooting Your Aube Thermostat Not Turning On
Here are some frequently asked questions to help you diagnose and resolve issues when your Aube thermostat isn’t turning on.
What’s the first thing I should check if my Aube thermostat is not turning on?
Begin by checking the power supply. Make sure the breaker connected to the thermostat is on. If it’s tripped, reset it. A loose wire connection can also cause an Aube thermostat not turning on.
Could a low battery cause my Aube thermostat not to turn on, even if it’s hardwired?
Yes, some Aube thermostats rely on batteries for backup or even primary operation of certain functions. If the battery is depleted, it could prevent the Aube thermostat from turning on completely. Replace the batteries to see if this resolves the issue.
What does it mean if the screen is blank, but I’m sure there’s power?
If the screen remains blank despite confirmed power, the thermostat might be faulty. It’s possible the internal components have failed, and the Aube thermostat not turning on indicates it requires professional repair or replacement.
How can I tell if the wiring is the problem when my Aube thermostat is not turning on?
Inspect the wiring connections at the thermostat and the heating system. Look for loose wires, corrosion, or any signs of damage. If you’re not comfortable working with electrical wiring, consult a qualified electrician to diagnose and repair any wiring issues causing the Aube thermostat not to turn on.
Well, that about covers it! Hopefully, you’ve got your Aube thermostat not turning on problem sorted out. Remember, if you’re still scratching your head about that aube thermostat not turning on, don’t hesitate to call in a pro. Happy heating!
