Frequently Asked Questions
How do I know if the TP540 (34-57310-K) is the right control for my spa?
Check the part number printed on the back of your existing topside control, or look for any of the cross-reference numbers listed above. If you're unsure, send us a photo of your current control along with your spa's make, model, and serial number, and we'll confirm compatibility before you order.
Will this control work with my existing Balboa spa pack?
The TP540 is designed to work with Balboa's BP Series spa packs. Most owners with an existing Balboa system can install this as a direct replacement, but we recommend confirming your spa pack model with our team first.
Is installation difficult?
No. The TP540 uses a 4-pin Molex-style plug connection, making it a straightforward swap for most DIY spa owners. Full disconnection of power at the breaker is recommended before starting any installation.
What if I can't find my part number?
No problem — this happens often. Just send us clear photos of your topside control, spa make and model, and serial number to fixmytub@gmail.com, and our team will track down the correct part for you.
Do you ship internationally?
Yes. As an international e-retailer, we stock this part across multiple regional warehouses to keep shipping times and costs down for our customers worldwide.
Get the Right Part, from the Right Region
As an international e-retailer, Western Tub and Pool warehouses parts across several regions to serve customers faster. Because of this, you'll notice a regional suffix added to part numbers:
- U — USA
- C — Canada
- E — Europe
- A — Asia
Some parts may be stocked in more than one region under these suffixes — this is normal, and simply reflects where the item ships from. Shipping times and rates will vary depending on the regional warehouse your part is sourced from.
