LED-94 on an Ideal Heating Logic Air: Trip detection
Short answer
On an Ideal Heating heat pump, LED-94 means: Trip detection. The heat pump stops until the fault clears or is reset. An engineer is needed to fix the cause.

What it means
The manual says: Trip detection.
Part involved: compressor, inverter PCB, main PCB.
When it shows: Overcurrent protection stop after compressor start processing completed, 10 consecutive times.
Likely causes:
- 1. Outdoor fan defective, foreign matter on heat exchanger, excessive ambient temperature rise 2. Main PCB 3. Compressor failure (lock, winding short) 4. Inverter PCB.
Is it safe?
| Does the heat pump stop? | Yes |
|---|---|
| Severity | Fault — needs a manual reset once the cause is fixed |
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
What you can check
- Note the code or fault message shown on the controller/Halo and when it appeared; check the heat pump's isolator and consumer-unit breaker are on. Check the outdoor unit is not blocked by snow, ice, leaves or stored items and that air can flow freely around it.
What the engineer will check
- Check air passages, HX fins, fan motor, recirculation of discharge air; replace inverter PCB, then main PCB, then compressor.
Who to ask for: Heat pump engineer; casing removal only by persons competent with R32 (A2L); refrigerant-circuit work requires Cat I/II F-gas certification (I&M p.75 warning).
Certification: F-gas Cat I/II for refrigerant work; electrical work by competent person.
