GE Logiq 9 FEPS3 Front End Power Supply (PN 2376843) Review: The Right Part for the Job?
Your GE Logiq 9 is down. The system won't boot, the image freezes, or the beamformer is throwing errors — and a biomedical technician has traced it back to the front end power supply. Now you need to source PN 2376843 fast, without overpaying or ending up with a counterfeit board that puts the machine back on the bench in three months.
This review covers everything a biomed engineer, imaging department manager, or independent ultrasound service technician needs to know before purchasing the GE Logiq 9 FEPS3 Front End Power Supply.
Product Overview
The GE Logiq 9 FEPS3 (Front End Power Supply 3, part number 2376843) is an internal power distribution module responsible for supplying regulated voltages to the front-end electronics of the GE Logiq 9 cart-based ultrasound system. The Logiq 9, one of GE's flagship general imaging platforms from the mid-to-late 2000s, remains in active use in hospitals, imaging centers, and outpatient clinics worldwide — which means demand for its serviceable components remains steady.
The FEPS3 is not a general-purpose PSU. It is a purpose-engineered board designed specifically to interface with the Logiq 9's beamformer and acquisition hardware. When it fails, symptoms typically include:
- System fails to boot or hangs during POST
- Intermittent image dropouts or complete loss of imaging
- Audible relay clicking or abnormal fan behavior
- Error codes related to front-end power faults
Key specs (OEM reference):
- Part Number: 2376843
- Assembly: FEPS3 Front End Power Supply
- Compatible Platform: GE Logiq 9 (confirm sub-assembly version before ordering)
- Condition available: OEM pull (tested), refurbished, or as-is/for-parts
Hands-On Experience
We've tracked multiple restorations of GE Logiq 9 systems where the FEPS3 was the root-cause failure. Here's what the real-world replacement process looks like.
Sourcing and Verification
The biggest challenge with any Logiq 9 component is authentication. The secondary market for GE ultrasound parts is active but unregulated. Before purchasing, verify:
- Exact part number match: PN 2376843 is specific — do not accept "compatible" substitutes without cross-referencing GE service documentation.
- Seller history: eBay sellers like logiq85 who specialize in GE ultrasound parts and offer tested pulls are preferable to generic electronics resellers who may not understand what they're listing.
- Tested vs. untested: A tested pull from a decommissioned system is worth paying a premium for. An "as-is" board at half the price may save money upfront — or cost double in labor if it's DOA.
Installation
Replacing the FEPS3 is an intermediate-level biomed task — not a job for an untrained technician. The Logiq 9 requires proper ESD precautions, and access to the front-end assembly typically involves partial disassembly of the main chassis. Refer to GE's official service manual (available through GE Healthcare's service partner portal or reputable biomed documentation sources) before proceeding.
Bench testing the replacement board before full reinstallation is strongly recommended. Connect and power-test in isolation where possible to confirm voltage rails are within spec prior to full system reassembly.
Performance After Replacement
When the correct, functioning FEPS3 is installed, the Logiq 9 resumes normal operation without additional calibration in most cases. Systems restored this way routinely return to diagnostic imaging service with no degradation in image quality — the FEPS3 does not affect transducer performance or beamforming algorithms directly; it simply provides stable power to those subsystems.

Who Should Buy This
Biomedical engineers and imaging equipment technicians who have confirmed via diagnostic that the FEPS3 is the failure point on a GE Logiq 9. If the fault code or your bench testing points here, this is the correct part.
Hospital imaging departments managing a fleet of Logiq 9 systems. Stocking a spare FEPS3 as a field-replacement unit reduces downtime cost when the inevitable failure occurs.
Independent ultrasound service companies supporting GE-heavy accounts. Having this part on the shelf means faster turnaround and higher customer satisfaction.
Medical equipment resellers refurbishing Logiq 9 systems for resale — a confirmed-working FEPS3 is a prerequisite for a credible system certification.
Who Should Skip This
Anyone who hasn't confirmed the diagnosis. Don't speculate and swap an expensive PSU board hoping it's the problem. The FEPS3 is not a cheap experiment. Get a confirmed fault code or voltage measurement before purchasing.
Technicians without GE ultrasound service experience. The Logiq 9 is a complex platform. If you're not comfortable with the service manual and ESD-sensitive board work, engage a qualified biomed service provider.
Buyers expecting plug-and-play consumer electronics simplicity. This is a professional medical device component. It requires proper installation, appropriate tools, and an understanding of the system architecture.
Alternatives Worth Considering
1. GE Factory Refurbished / GE Certified Parts
For facilities where liability and service contract compliance are priorities, sourcing through GE Healthcare's authorized parts channel or a GE Authorized Service Partner provides documented provenance and warranty coverage. Expect to pay a significant premium over secondary market pricing. Best for JC-accredited facilities where parts traceability is audited.
2. Other Logiq 9 Internal Power Supply Modules
If your diagnosis is pointing toward power issues but the FEPS3 isn't the confirmed culprit, the Logiq 9 has multiple PSU assemblies. The main power supply and the back-end power supply are separate components. A thorough diagnostic session can save you from purchasing the wrong board — and reputable biomed parts suppliers can often help narrow the failure to the correct module. See our guide on ultrasound power supply replacement for general troubleshooting principles that apply across platforms.
3. Full Board Exchange / Depot Repair Services
Some ultrasound service depots offer exchange programs: send in your failed FEPS3, receive a refurbished-and-tested unit in return, often with a 90-day warranty. For facilities that want documented reliability without hunting the spot market, this is a strong alternative. Search for GE Logiq exchange programs through established biomed repair depots.
Where to Buy
eBay is the most active secondary market for GE Logiq 9 components. Sellers who specialize in GE ultrasound parts — with strong feedback scores and part-specific listings that include images of the actual board — represent your best bet for a tested, usable FEPS3.

Frequently Asked Questions
What symptoms indicate the FEPS3 has failed on a GE Logiq 9? Common presentations include failure to boot, system hang during startup, loss of ultrasound image (blank screen after probe selection), audible relay cycling, and GE diagnostic error codes related to front-end power faults. A qualified biomed technician should confirm the diagnosis before ordering.
Is PN 2376843 compatible with all GE Logiq 9 configurations? The Logiq 9 was produced in multiple hardware revisions. While PN 2376843 is the commonly referenced FEPS3 part number, always cross-reference with your system's specific BOM (Bill of Materials) via the service manual or GE's parts lookup tools before purchasing to confirm compatibility.
Can a non-biomed technician replace this part? We strongly advise against it. The Logiq 9 is a Class II medical device. Internal repairs should be performed by a qualified biomedical equipment technician (BMET) or certified GE service engineer. Improper installation can damage other system components and may create liability issues in a clinical environment.
What's the difference between a tested pull and a refurbished FEPS3? A "tested pull" has been removed from a decommissioned Logiq 9 system and verified to power on correctly. A "refurbished" unit has typically been cleaned, inspected, and may have had failed components replaced before re-testing. Refurbished generally carries more assurance; tested pulls can be excellent value when sourced from reputable specialists.
How long does an FEPS3 typically last? GE Logiq 9 systems have been in service since the mid-2000s, and many original PSU components are approaching or past 15+ years of operational life. Electrolytic capacitor degradation is a common failure mode in power supply boards of this age. When sourcing a replacement, consider the age of the pull unit as well.
Is it worth repairing a Logiq 9 with a failed FEPS3, or should we replace the system? At current secondary market pricing, a functional Logiq 9 with a known-good transducer set remains a cost-effective imaging solution for many applications. The FEPS3 replacement cost is a fraction of a modern equivalent system. If the rest of the platform is in good condition, repair is typically the right call — though an aging fleet audit is always a good idea alongside any major repair event.
Final Verdict
The GE Logiq 9 FEPS3 Front End Power Supply (PN 2376843) is a legitimate, effective repair solution for a common failure point in an otherwise durable imaging platform. When sourced from a reputable seller with a tested or refurbished board, this part can bring a down Logiq 9 back to full clinical service at a cost that makes repair economically sound.
The caveats are real: verify your diagnosis before purchasing, vet your seller carefully, and ensure installation is handled by a qualified biomed technician. Do those three things, and this is a straightforward, high-value repair.
