Fire Magic 23729-70 Aurora A540 & A430 (Pre 2016) Lid Spring Kit

What Problem This Part Solves

The stainless steel hood on a Fire Magic Aurora grill is substantial, and its spring mechanism helps offset that weight during normal use.

As the original spring assembly ages, you may experience:

• A hood that feels significantly heavier to lift
• Reduced spring assistance
• Rough or uneven lid movement
• A broken or damaged spring
• Difficulty raising the hood
• Hood movement that no longer feels like it did when the grill was new

Replacing the worn assembly with Fire Magic 23729-70 restores the spring-assist mechanism on compatible pre-2016 A430 and A540 grills.

Compatibility / Fits Models

Fire Magic 23729-70 is designed for select:

• Fire Magic Aurora A430
• Fire Magic Aurora A540
• A430i built-in configurations using the applicable pre-2016 hood
• A430s portable configurations using the applicable pre-2016 hood

• A540s portable configurations using the applicable pre-2016 hood

Fire Magic's historical Aurora documentation confirms the A430 and A540 as established models within this grill family, while its current replacement-parts catalog specifically assigns 23729-70 to the pre-2016 A43 and A54 platforms.

Fits most grills within this series—confirm model number and production year before ordering.

Important: Pre-2016 vs. Current A430/A540

The production year is especially important for this part.

• 23729-70 – Lid Spring Kit for Aurora A430 & A540 – Pre-2016
• 23729-72 – Current Oven Hood Spring Kit for Aurora A430 & A540 and select Choice grills

Fire Magic lists these as separate replacement components. The current 23729-72 is also used on Choice C430, C540 and C650 models.

Therefore, 23729-72 should not automatically be substituted for 23729-70 on an older grill.

Installation / Use Instructions

1. Turn off the grill's gas supply and allow the grill and hood to cool completely.
2. Securely support the grill hood before removing any existing spring hardware. The hood is heavy, and the spring mechanism can be under tension.
3. Remove the original spring components and install the 23729-70 kit in the corresponding factory mounting positions. Carefully test hood operation after installation.

Caution: Lid springs store mechanical energy. Keep hands and fingers clear of pinch points and always support the hood during service. Professional installation is recommended if you are unfamiliar with spring-loaded grill hood mechanisms.

FAQ Section

Does Fire Magic 23729-70 fit my grill?
It is specifically listed for pre-2016 Fire Magic Aurora A430 and A540 grills. Fire Magic's replacement-parts catalog identifies the applications as size codes A43 and A54.

What does the 23729-70 spring kit do?
It provides spring assistance for the grill's heavy hood, reducing the effort required to open the lid and helping restore smoother hood movement.

Does this fit both built-in and portable Aurora grills?
The A430 and A540 were offered in both built-in and portable configurations. The critical factors are the grill's model, production year, and original hood/spring configuration, so confirm the original part number before ordering.

Is 23729-70 the same as 23729-72?
No. Fire Magic currently identifies 23729-70 for pre-2016 A430/A540 grills, while 23729-72 is the current oven hood spring kit for A430/A540 and select Choice models.

How do I know whether I need 23729-70 or 23729-72?
If you have a pre-2016 A430 or A540 using the earlier spring system, Fire Magic specifies 23729-70. Current A430/A540 applications use 23729-72. Checking your grill's serial/model information and original parts diagram is the safest way to distinguish them.
