🎛️ Board Functions

This board provides control of all standard functions in the Coleman/MAAX 100 Series 115/117 model spa:

• Pump Control — Primary pump operation (pump speeds as configured for the specific model)
• Heater Control — Manages spa water heating with temperature regulation and hi-limit protection
• Extended Filter Cycles — Programmed with extended filter cycle timing specific to the 115/117 system designation
• Lighting — Spa light on/off control
• Ozone — Controls ozone generator operation if installed
• Temperature Display — Works with Cal Coop 4-button topside for temperature monitoring and adjustment

⚠️ Chip-Specific Programming: The 115/7R1(x) chip contains programming custom-tailored by Coleman for the 100 Series 115/117 spa models. This means filter cycle timing, temperature defaults, and pump behavior are programmed specifically for these spa models — which is why using any other chip (such as the 105/7R1C or 135R1) will result in incorrect system behavior even if the boards look identical.

⚙️ Installation Requirements

⚠️ IMPORTANT: All electrical work must be performed by a licensed electrician in compliance with the National Electrical Code (NEC) Article 680 and all applicable local codes.

Pre-Installation Checklist

• [ ] Verify chip designation on your existing board reads 115/7R1 (any letter suffix)
• [ ] Confirm spa is a 2001 or 2002 Coleman/MAAX 100 Series (model 115 or 117)
• [ ] Note all component wiring before disconnecting (photograph if possible)
• [ ] Confirm topside panel is the Cal Coop 4-button (101227) or original equivalent with 8-pin phone plug
• [ ] Disconnect ALL power at circuit breaker and GFCI before starting
• [ ] Allow capacitors to discharge — wait at least 5 minutes after power-off
• [ ] Verify this is a board failure and not a pressure switch, sensor, or wiring issue before ordering

Electrical Requirements

Requirement	Specification
GFCI Protection	Class A GFCI required — NEC Article 680

🔍 Troubleshooting Before Replacing the Board

On legacy Coleman spa systems, board failure is often misdiagnosed. Before ordering a replacement circuit board, check these components first:

Symptom	More Likely Cause	Check First
Heater not working	Failed high-limit sensor or pressure switch	Test sensors and pressure switch
Spa won’t power on	GFCI tripped, blown fuse, or bad power connection	Reset GFCI, check fuses and wiring
Panel unresponsive	Damaged topside panel or cord connection	Test panel; inspect 8-pin phone cord
Intermittent operation	Loose wiring connection	Inspect all connectors and terminal blocks
Pump not running	Failed relay on board, or failed pump itself	Verify pump operates when direct-tested

ℹ️ On older Coleman spas, degraded wiring, corroded connectors, and failed sensors are common failure points. Replacing the circuit board without checking these first can result in continued problems even after board replacement.

❓ Frequently Asked Questions

Q: How do I confirm this board fits my spa? A: Check the chip number on your existing circuit board. It will be printed on a white label sticker, usually near the center of the board or on the transformer/relays. The chip number must read 115/7R1 followed by any letter. Also confirm your spa is a 2001 or 2002 Coleman or MAAX 100 Series (model 115 or 117). Contact Parts4Tubs with your spa’s full model and serial number if you cannot locate the chip label.

Q: Will this work for my 1999 or 2000 Coleman 100 Series spa? A: No. The 1997–2000 100 Series spas used a different board with chip designation 105/7R1C (Coleman PN 101096). The boards look very similar but the chips are programmed differently. Using the wrong chip will cause incorrect filter cycles and other operational issues.

Q: My spa is a 2003 or 2004 model — will this work? A: No. Coleman 100 Series spas from 2003 to 2005 use the board with chip designation 135R1(x), Coleman PN 103093. The 101285 is specifically for 2001–2002 models.

Q: Is this board also used in California Cooperage spas? A: Yes. California Cooperage hot tubs from approximately 1999–2002 used the same Coleman/Balboa 100 Series control system with the 115/7R1(x) chip board. The compatible topside panel (101227) is described as a “Cal Coop 4-button” panel and works with both Coleman and California Cooperage spas using this system.

Q: What topside panel works with this board? A: The current replacement for the original topside panel is the Coleman Cal Coop 4-button panel, PN 101227 (Balboa PN 51669). This replaces the discontinued original panels 101173 and 101225. It connects with the same 8-pin phone-style cord as the circuit board.

Q: Is this a hard-to-find board? A: Yes. This is a legacy Coleman OEM board with limited ongoing production. It is available as a special order with a 2–5 business day lead time. Once ordered, it is non-returnable and cannot be canceled. Contact Parts4Tubs to confirm current availability before placing your order.

Q: Do I need a licensed electrician to install this? A: Yes. NEC Article 680 and most local jurisdictions require a licensed electrician for all hot tub electrical work including circuit board replacement.

Q: What is the warranty? A: Please contact Parts4Tubs to confirm current warranty terms. Note that Coleman historically offered a limited 90-day factory warranty on circuit boards, though Balboa’s standard warranty is 1 year. Parts4Tubs will clarify the applicable warranty terms at time of order.

Finding and identifying a replacement Hot Tub Circuit Board (PCB)

If you are looking to replace a failed PCB on your Hot Tub’s spa pack, then quite often identifying the part that you need can be the hardest thing.

Firstly, you are looking for a model number on the actual circuit board itself. Having the model or serial of your hot tub is not going to help at this point, you need to find the number on the PCB itself.

Now, with certain brands of PCB, the number of the replacement PCB that you need is not going to match identically the one you are replacing. Why is that I hear you ask?

Well, normally, it is an updated version. This means that it might have updated firmware on the PCB or be a later revision. Normally, this means that the part number would be slightly different. This is usually indicated with a “12345678 -x” at the end of that part number where x indicated a firmware revision.

In some cases, there will be some following letters on the part number of the circuit board, “12345678 -x MAS” this can indicate that the PCB was used for an OEM meaning it was produced for a certain hot tub manufacturer and the letters identify the manufacturer.

This means if you source an original PCB, it will not have the letters, but will in most cases work just fine.

It can be confusing I know!

What if you can’t find a model number?

If you can’t find a model number on the PCB itself, then you need to look for a model number on the spa pack. Normally, there is a sticker on the outside of the spa pack that tells you the current ratings and input voltages etc and this will have a model number.

In general, most spa packs in the USA are manufactured by Balboa, Hydro-Quip, ACC or Gecko. I know I am generalising here, but if you have a spa pack that has the brand of your hot tub on, it will be an OEM so the key is identifying who made the original box.

From there, you can normally find an original PCB that you will be able to switch out.

For example, the Balboa VS (value series) is a very popular spa pack that has been used by multiple hot tub manufacturers under their own brand names. Whatever they have called it, strip it back and it is still a Balboa VS.

Visual Inspection

One of the most important things you can do when you are looking for a replacement is to visually inspect the PCB that you have versus the picture online of the replacement you are considering. They need to look the same even if there are the differences in firmware revisions or OEM part numbers, you should be visually replacing a PCB that looks like the one you have.

Configuring a replacement Hot Tub Circuit Board (PCB)

When you get a new PCB, you are more than likely going to need to configure it. Most PCBs have a number of different modes and setups that the can operate in. For this, you will need to manual or spec sheet to guide you.

For things like DIP switches, most of the time you can copy the settings from your original circuit board. You are looking for things like setting the voltage as a lot of PCBs can be configured to run on both 115V and 230V.

You may need to move jumpers or even wires to configure voltages – the key here is that you read the schematic and don’t expect the PCB to just work out of the box – it usually doesn’t.

Troubleshooting a Hot Tub Circuit Board (PCB)

Here are some common things you will see when you replace a PCB on a hot tub.

You press the buttons on the topside control and they don’t control the right parts (pumps or blower etc) – this is a mode configuration thing and you will either need to change some DIP switches on the PCB or an internal or low level programming mode on the topside control. Check the manual for how to do this.

You turn on the hot tub and it trips the breaker – it is not common for a new PCB to fail out of the box (I have not seen one yet!) However, a common mistake is that the voltage has not been set correctly. If it is set for 115V and then you try and turn it on, the current draw will be a lot more (twice) than expected and the breaker will trip.

To check this, unplug all of your kit – heater, pumps, blower and then turn on the PCB. If it trips with nothing plugged in, usually the voltage is incorrectly set and what is happening is that live current is being sent to the ground – because you have 4 wires into the PCB rather than 3. Current on the ground loop causes the trip. Check the settings to make sure it is configures for 230V.

It might not trip until you physically turn on a pump or a blower. As mentioned, if the pack is set to 115V and your pump is meant for 230V, it will draw twice the current at half the voltage and trip your breaker. Check the manual for info on how to set the voltage.
