Merrimack Fan Blade Direction Control: Quick Instructions

The most common question we get on the Merrimack is how to change the blade direction. There is no remote setting for this on the standard #40094 — it’s a physical slide switch on the motor housing, just above the blades.

1. Turn the fan off at the pull chain and wait for the blades to stop completely.
2. Find the small slide switch on the side of the motor housing.
3. Summer: switch down — blades spin counterclockwise and push air straight down for a breeze.
4. Winter: switch up — blades spin clockwise on low speed, pulling cool air up and pushing the warm air at the ceiling back down the walls.
5. Restart the fan and check from below: counterclockwise = cooling, clockwise = heat recovery.

Full explanation of when and why to reverse it (with diagrams) in our ceiling fan direction guide for summer and winter. Switch broken, or missing your remote? See Harbor Breeze replacement parts & remotes.

Which Merrimack Do You Have?

There are two, and the parts are not always interchangeable. Before you buy anything, find
the model number. It is printed on a label on the top of the motor housing, visible once the
canopy is lowered, and on the original box if you still have it.

• Merrimack is model #40094, item #0080443,
  the 52 inch five blade version sold through Lowe’s.
• Merrimack II is the later revision. Same body, different receiver in most
  units, which matters when you replace a remote. If your handset code starts TR214D rather than
  TX007, you almost certainly have the II.

If the label is gone, the fastest tell is the battery door of the remote. The code printed
inside it tells you which receiver is fitted, and that is the number that decides which
replacement remote works.

The Manual

The full Harbor Breeze Merrimack manual is embedded above and you can also
open the original PDF if you would rather
print it or keep it on your phone. It covers the wiring diagram, blade balancing and the
factory parts list.

Everything below is the part the manual does not tell you: what actually goes wrong with
this fan after a few years, and what to buy to fix it.

Merrimack Problems, and What Each One Usually Is

Symptom	Most likely cause	What to do
Fan hums but blades will not start	Failed capacitor	Replace the CBB61. Match the microfarad values printed on the old one, not the fan model
Only some speeds work	Capacitor, or the pull chain switch	If the remote changes nothing on any speed it is the capacitor. If the chain feels loose it is the switch
Remote does nothing, light and fan both dead	Receiver has lost pairing, or the handset has failed	Try re-pairing first. Kill power at the breaker for 30 seconds, restore it, then hold the pairing button within 30 seconds
Light works, fan does not	Capacitor or receiver fan channel	Capacitor is far more common and much cheaper. Try it first
Pull chain came off in your hand	Chain switch broken internally	Replace the ZE-268S6 switch. It is a four wire, three speed part
Fan wobbles	Blade balance or a loose downrod pin	Check the downrod pin and screws before you reach for a balancing kit. Loose hardware causes more wobble than unbalanced blades
Runs backwards	Direction switch position	See the blade direction section below. It is a switch, not a fault

Replacing the Remote or Receiver

This is the single most common Merrimack repair, and the reason most people land on this
page. The handset and the receiver are a matched pair, so the code inside the battery door
decides what you buy.

• Handset code A25-TX007 or A25-TX007-R1: the
  Anderic RRTX007
  is the direct replacement.
• Handset code TR214D: use the
  Anderic RRTR214D
  instead.

Pairing: turn the power off at the breaker, wait 30 seconds, turn it back on,
then press and hold the pairing button on the new handset within the first 30 seconds. If you
miss that window, cut the power and start again. Nothing is broken, the receiver just stops
listening.

If a new handset does not fix it, the receiver in the canopy has failed rather than the
remote. At that point you are choosing between a receiver swap and a new fan, and on a fan this
age the new fan is often the better call.

Installing or Reinstalling a Merrimack

Two things cause most of the callbacks I get on this model. First, the downrod pin: it must
go all the way through and the retaining clip has to be seated, or you get a wobble that no
amount of blade balancing will fix. Second, the canopy screws: leave them slightly loose while
you hang the fan and you will fight the wiring the whole way.

Get the drop height right before anything else. Our
downrod length chart covers
what length you need for your ceiling. On a standard eight foot ceiling the Merrimack is usually
fitted with the short rod it ships with.

If It Is Beyond Repair

A capacitor is under fifteen dollars and worth trying. A receiver plus a handset starts to
approach the price of a new budget fan, and at that point the honest answer is to replace it.

The Merrimack was a Lowe’s house-brand fan, so the natural like-for-like replacement is
another Harbor Breeze of the same size. We compare the current range in our
Harbor Breeze comparison.
