Interactive Guide: 3 Functional Strategies to Address nest no power to rh wire:
SOLUTION 1: Check the Safety Switch on the Furnace
- The furnace’s safety switch ensures the unit doesn’t operate while serviced. First, open the furnace panel.
- Locate the safety switch – typically found on the inside door. If not appropriately engaged, the furnace may not power up.
- Make sure it’s securely positioned. If tripped, reset the switch.
SOLUTION 2: Inspect the Evaporator Condensate Pan
- The condensate pan collects water produced during the cooling process. Open your HVAC unit to find it.
- Excessive water can indicate a clogged drain line or other issues. Clear away any water buildup.
- If there’s a significant accumulation, inspect the drain pipe for clogs and clear them to ensure proper drainage.
SOLUTION 3: Examine the Rh Wire Connection
- The Rh wire is integral to the thermostat’s functioning. Inspect it for any signs of wear, tear, or disconnection.
- Blown fuses or malfunctioning transformers can also disrupt power. If uncertain about your diagnosis, consider consulting with a professional or the product’s manual.

What does an Rh wire do?
The Rh wire, often termed the “heating power wire,” is essential for transmitting power to the heating component of your HVAC system.
Are R and Rh wires the same?
No, they aren’t. Though they’re both related to heating, the distinction lies in their specific functionalities. In multi-transformer systems, the R wire originates from the cooling transformer, while the Rh wire originates from the heating transformer.
Should the Nest be connected to Rc or Rh?
The correct connection largely depends on the type of HVAC system you have. Generally, Rh is reserved for heating systems, and Rc is for cooling. Always refer to your system’s specifications or consult a professional for guidance.
What to do if my Nest still doesn’t power up after trying the solutions?
If your Nest thermostat still isn’t functioning after troubleshooting, it might be a deeper technical issue or a defective product. It’s advisable to contact Nest’s customer support or consult with an HVAC technician.
Is there a risk of damaging my HVAC system while troubleshooting?
While most troubleshooting steps are designed to be user-friendly, there’s always a slight risk involved. Always turn off the power to your HVAC system before inspecting any wires or connections. If you’re uncomfortable or unsure about a procedure, seek professional assistance.
