Electronics, Valves and Flow Sensors for GE Anesthesia Machines: Carestation, Aisys, Aespire, 9100C NXT — 12 Spare Parts
GE anesthesia machine electronics and valves: board 1011-8000-000-S, valve 1503-3854-000-S, flow sensors M1174442-S1 and 2087640-001-S, valve 0211-1454-100.
Electronics and valve assemblies are the part of the GE anesthesia machine fleet that puts the operating room on hold most often. A gas mixing board, a flow sensor or a system disk do not wear out gradually: they fail, and the anesthesia room stands idle until the delivery arrives. Hence the practical conclusion for a service department — keep a spare parts stock by specific PN, rather than assembling a kit "by eye" before an inspection.
This guide covers twelve items that have entered the MediAccessori catalog for GE anesthesia machines (Carestation, Aisys, Aespire, 9100C NXT): boards, valves, flow sensors, a cooling assembly and a scheduled maintenance kit. For each item the official catalog description, compatible equipment, an approximate price in rubles and stock availability are given.
1. Why anesthesia machine electronics need a dedicated reserve
Scheduled maintenance of an anesthesia station is predictable: consumables (circuits, flow sensors, soda lime, seals) are purchased in cycles. Electronics behave differently — they belong to the "before failure" category, and a failure, as a rule, happens in the middle of a surgical day.
Two typical downtime scenarios:
- •a flow sensor or a board fails — the machine is taken out of service and the department waits for delivery (lead time is confirmed at order placement);
- •the system disk is outdated or damaged — the machine formally works, but the service engineer cannot perform configuration and updates.
Therefore it makes sense for a service department's reserve to hold three categories: quickly replaceable sensors, valves and seals; power and control boards for the most heavily loaded machines; and consumable kits for scheduled maintenance.
2. Boards: gas mixing, display and power
PN 1011-8000-000-S — air and oxygen mixing board
No official catalog description is provided for this item; the card states the purpose — air and oxygen mixing board, equipment — GE anesthesia machine.
Approximate price: 286,000 ₽ · Availability: 10 pcs.
This is the most expensive item in the selection. The purchasing logic here differs from consumables: a gas mixing board is bought not "for every machine" but as a reserve for a group — one assembly covers the downtime risk for several stations at once.
PN M9100000-S — display control board
No official catalog description is provided. Purpose — display control board for a GE anesthesia machine; the compatibility section of the card lists the 9100C machine.
Approximate price: 49,500 ₽ · Availability: 5 pcs.
The symptoms that lead to checking this particular board: no image, a "frozen" screen, incorrect display of ventilation parameters while the machine's mechanics are running.
PN 2076733-001-S — C600 power board
Official catalog description (English): ACIN 100-240V, DCOUT: 12.6V, ECM140US12-A-XA1049
Equipment: GE Carestation 600 Series anesthesia machine · Approximate price: 22,000 ₽ · Availability: 5 pcs.
A power board is a typical candidate for failure after voltage surges in an operating unit. The item is tied to Carestation 600 Series stations, that is, it covers the most widespread GE family in Russian clinics.
PN 2107870-120 — system disk
No official catalog description is provided. Compatible equipment on the card — 9100C, NXT.
Approximate price: 33,000 ₽ · Availability: 1 pc.
The system disk is an item many clinics do not keep in stock — wrongly so: without a working medium the service engineer is limited in diagnostics and software updates. Availability of only 1 pc. in stock means the item should be reserved in advance, for a specific machine.
3. Valves and the gas path
PN 1503-3854-000-S — VALVE FLOW CONTROL 120 LPM 12V MPOS
Official catalog description (English): The Flow Control Valve comes as a part of the vent engine manifold of an Anesthesia Delivery System. It is used to control the gas flow through the Medium Pressure Oxygen Service (MPOS) manifold, which is provided as a part of the vent engine in Breathing Circuit Gas (BCG) of the ventilator. The assembly comes into contact with oxygen-enriched gas in the range of 50 to 3000 kPa. The components are corrosive resistant and hence it is highly efficient to use in medical environments.
Equipment: Aespire · Approximate price: 132,000 ₽ · Availability: 3 pcs.
This is a flow control valve within the ventilator block manifold: it is responsible for gas supply through the MPOS manifold. Signs of wear — unstable flow delivery, calibration errors, a discrepancy between commanded and actual flow.
PN 1006-8345-000 — nitrous oxide needle valve
No official catalog description is provided. Compatible equipment — GE Aespire.
Approximate price: 27,500 ₽ · Availability: 5 pcs.
A needle valve is a precision metering assembly; it is selected by machine, not "by size". If a clinic runs Aespire stations, the item belongs in the mandatory gas path reserve.
PN 2071067-001-S — check valve assembly
Official catalog description (English): CHECK VALVE ASSY
Equipment: Carestation 600 Series · Approximate price: 4,400 ₽ · Availability: 10 pcs.
A check valve is an inexpensive item with a high cost of downtime: a malfunction shows up as reverse gas flow and unstable ventilation parameters. At 4,400 ₽ and 10 pcs. in stock, the assembly is convenient to keep in permanent reserve for the entire Carestation 600 Series fleet.
PN 0211-1454-100 — valve
Official catalog description (English): VALVE FLPR 1.062D .875L W/TPR STEM SIL BCG
Compatible equipment is not listed on the card. Approximate price: 2,200 ₽ · Availability: 5 pcs.
Since the list of compatible equipment is not declared, before purchasing for a specific machine it is worth confirming the installation location against the service documentation.
4. Flow sensors
PN 2087640-001-S — autoclavable respiratory flow sensor
Official catalog description (English): Flow sensor – autoclavable: Newest flow sensor designed to work in the presence of moisture with pressure sense lines kink prevention. Single piece flow sensor body design with titanium flapper. Will last for a minimum of 1 year. Can be used in MRI environments.
Equipment: GE Datex Ohmeda · Approximate price: 38,500 ₽ · Availability: 20 pcs.
A respiratory flow sensor is a consumable element of the breathing circuit that is removed for processing. Availability of 20 pcs. and a price of 38,500 ₽ make this item the most convenient candidate for permanent reserve: replacing the sensor is a routine procedure, not a repair.
PN M1174442-S1 — flow sensor
Official catalog description (English): A Differential Pressure Sensor Assembly - Phantom is a special type of pressure sensor that measures the change in pressure across two ports on a device. The part Assembly-WXC is a necessary part of the GE 9100C ventilator. The tube and cables are made up of high quality materials and the assembly is more stable under stringent conditions.
Equipment: 9 Series -ACS · Approximate price: 11,000 ₽ · Availability: 10 pcs.
Note the discrepancy: on the catalog card the item is tied to 9 Series -ACS, while the manufacturer's description mentions the 9100C machine. For a specific machine, compatibility is confirmed by a service engineer against the serial number.
5. Cooling and data exchange: PN M1220157
Official catalog description (English): OEM PART, KIT FAN COM EXPRESS, Electro-Mechanical
Equipment: GE Carestation 600 Series anesthesia machines · Approximate price: 8,800 ₽ · Availability: 5 pcs.
The item relates to cooling and data exchange in the ventilator block. Electronics overheating is an underestimated cause of "floating" board failures, so the assembly is worth keeping in reserve alongside the power boards.
6. Scheduled maintenance: 9100C NXT kit 2099998-001-S
Official catalog description (English): 9100C NXT MAINTENANCE KIT YEAR ONE
Equipment: 9100C NXT · Approximate price: 4,180 ₽ · Availability: 20 pcs.
The first-year service kit is the simplest way to cover scheduled maintenance: one item instead of selecting individual consumable elements. Availability of 20 pcs. allows servicing the 9100C NXT fleet by calendar rather than by failure.

8. Typical faults and diagnostic sequence
A practical sequence for a service department:
- •Unstable flow or calibration errors — check the flow sensor (2087640-001-S, M1174442-S1) and the flow control valve (1503-3854-000-S).
- •Reverse flow, unstable circuit pressure — check the check valve assembly (2071067-001-S) together with the breathing circuit seals.
- •The machine does not turn on or shuts down under load — check the power board (2076733-001-S) and the cooling assembly (M1220157).
- •No image or a "frozen" screen while the mechanics are running — check the display control board (M9100000-S).
- •Software cannot be updated or configuration cannot be performed — check the system disk (2107870-120).
Diagnostics should start with the cheapest replaceable item and move toward the most expensive: sensor, valve, board, disk. This order saves the department's budget.
9. How to plan the budget and the reserve
Approximate logic for an annual plan for a department with a fleet of GE anesthesia stations:
- •maintenance kit 2099998-001-S and seals — an annual purchase by the number of machines;
- •flow sensor 2087640-001-S (20 pcs. in stock, 38,500 ₽) — a permanent reserve item;
- •inexpensive valves and assemblies 2071067-001-S (4,400 ₽) and 0211-1454-100 (2,200 ₽) — reserve for the entire fleet;
- •boards 2076733-001-S, M9100000-S and board 1011-8000-000-S — purchased into the service department's stock, one per group of machines;
- •system disk 2107870-120 — for a specific machine, given availability of 1 pc.
