# Troubleshooting "@@@--- Failed to get temperature" error on the MiSeq

**Background**

The "@@@---Failed to get temperature" warning message indicates that the MiSeq was unable to read temperature information from a sensor. This warning typically does not cause the run to stop, and sequencing can often continue to completion with good run metrics.

**Troubleshooting steps**:

1. Power cycle the MiSeq after run completes following the instructions in [How to Power Cycle the MiSeq](/instrumentation/miseq-ruo/instrumentation-miseq-ruo-reference_material-list/000001894.md).
2. If the MiSeq Control Software (MCS) restarts without any issues, proceed starting a new sequencing run.
3. If the sequencing run shows any unexpected metrics or stops mid-run, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/) for further assistance.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://knowledge.illumina.com/instrumentation/miseq/instrumentation-miseq-troubleshooting-list/000001453.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
