Warranty Replacement Process
If your Mysa thermostat develops a defect covered under our warranty, we'll replace it. Here's the step-by-step process for requesting a warranty replacement.
Before You Submit a Claim
Before requesting a warranty replacement, try these steps:
- Check our troubleshooting guides in the Mysa app or knowledge base for common solutions
- Restart your thermostat by toggling the circuit breaker off and back on
- Ensure your thermostat firmware is up to date via the Mysa app
- Confirm the issue is not related to your home's electrical wiring or heating system
Tip: Many common issues can be resolved through troubleshooting without needing a replacement. Check our support articles or contact us for help before assuming a defect.
How to Submit a Warranty Claim
- Email support@getmysa.com with the following information:
- Your order number or proof of purchase
- Date of purchase
- Description of the issue you're experiencing
- Photos or videos showing the defect (if applicable)
- Steps you've already tried to resolve the issue
- Our support team will review your claim and may ask follow-up questions or request additional troubleshooting steps
- If the issue is confirmed as a warranty-covered defect, we will authorize a replacement
Important: You must provide proof of purchase (order confirmation, receipt, or invoice) to process a warranty claim.
What Happens After Approval
Once your warranty replacement is approved:
- A replacement thermostat will be shipped to you at no cost
- Replacement shipments follow standard shipping timelines for your region
- You may be asked to return the defective unit (Mysa provides a prepaid return label)
- In some cases, a replacement may be shipped before the defective unit is returned
Note: Mysa reserves the right to request the return of the defective unit. Return instructions will be provided with your replacement confirmation.
Warranty Replacement Timeline
- Claim review: 1-3 business days after submission
- Replacement shipping: Standard shipping times apply (3-10 business days depending on location)
- Total estimated timeline: 5-15 business days from claim submission to receiving the replacement
What's Not Covered
Warranty replacements are not provided for issues caused by:
- Improper installation or wiring
- Physical damage (drops, water exposure, impact)
- Unauthorized modifications or repairs
- Power surges or electrical issues in the home
- Normal wear and tear
- Use with incompatible heating systems
Caution: Attempting to open, modify, or repair the thermostat yourself will void the warranty.
