Heat strips provide electric resistance heat in a heat pump system. If your Mitsubishi Electric system is not heating properly, a sudden change in your electric bill, unusual sounds, a burning odor, or a tripped breaker may be reasons to arrange an inspection. None of these symptoms alone confirms that a heat strip has failed. We diagnose the system before recommending replacement.

We replace heat strips on Mitsubishi Electric systems across Davenport with genuine Mitsubishi Electric parts. Our line is answered 24/7, including nights and weekends, with no extra charge for nights or weekends. Dispatch may be available the same day or at the next available time.

When Heat Strip Replacement May Be Needed

A technician may recommend replacement if testing identifies a damaged or failed heating element, or if another condition has made the heat strip unsafe or unreliable. Similar symptoms can also come from controls, wiring, airflow, or other equipment problems, so a bill increase or uneven heat is not proof that a particular part has failed.

Before replacement, the technician can check the system and its equipment information to identify the correct part. The recommendation should account for compatibility and applicable warranty requirements. A genuine Mitsubishi Electric part is used for the replacement when appropriate.

What to Expect During Replacement

  • Diagnosis: The technician checks the reported problem and inspects the heat strips, controls, wiring, airflow, and relevant safety devices. Findings guide the repair recommendation.
  • Replacement plan: If replacement is needed, the technician confirms the part and system compatibility, explains the recommended work, and addresses warranty considerations before proceeding.
  • Safe electrical work: A qualified technician isolates power and verifies the equipment is de-energized before working on high-voltage components. Inspection, testing, and replacement of elements, sequencers, wiring, and safety controls are technician work.
  • Installation and checks: The technician installs the approved replacement, checks connections and related components, and tests system operation and safety controls.
  • Service record: The work and findings can be documented for your equipment history and future service.

What Homeowners Can Safely Do

Keep the air filter maintained according to the equipment instructions, and note changes such as reduced heat, a higher-than-usual bill, unusual sounds, or breaker trips. These observations can help the technician, but they do not identify a failed part by themselves.

If you notice a burning odor, turn the system off at the thermostat only if you can do so safely. Do not open the equipment, touch wiring, or operate the breaker or electrical panel. If you see smoke or flames, or feel unsafe, leave the area and contact emergency services. Otherwise, call for HVAC service and do not restart the system until it has been checked.

Do not attempt to replace heat strips or test high-voltage components yourself. Leave electrical inspection, diagnosis, and repair to a qualified technician.

After Replacement

The technician should verify operation and relevant safety controls after the work. Ask what was replaced, what testing was completed, and whether any follow-up or maintenance is recommended. Routine professional inspection may help identify wear or other concerns, but it cannot guarantee that a component will not fail.

Are Mitsubishi Electric heat strips dangerous?

Heat strips use high-voltage electricity and should be serviced by a qualified technician. Proper diagnosis and safe work practices matter. If you notice a burning odor, follow the safety steps above and arrange service; the odor alone does not establish its cause.

What are signs of a heat strip problem?

Reduced or uneven heat, a change in electric use, unusual sounds, a burning odor, or a tripped breaker can be reasons to request an inspection. These signs can have several causes and do not prove that a heat strip or sequencer has failed.

Can I replace heat strips myself?

No. Heat strip replacement involves high-voltage electrical components and should be handled by a qualified technician. Do not open the equipment or attempt electrical testing or repair.

How does the technician determine whether replacement is needed?

The technician inspects and tests the system, including the heat strips and related controls, wiring, airflow, and safety devices as appropriate. The findings determine whether replacement is recommended or another repair is needed.
