The manual states that on-and-off blinking of load indicates the load is less than minimum.
Minimum load draw is .3 amps and 40 watts.
http://waterheatertimer.org/pdf/Lutron-MA-T51-T53-timer-manual.pdf

Generally a bath fan is 1/6 Hp or 3 amps... exceeding the minimum.
Manual indicates that wiring error can also cause on-off blinking.
MA T530 replace single pole switch,,, and either wire from switch can connect to either brass screw on timer.
This timer will not replace 3-way switch.

Defective product is also possible/ call Lutron 800-523-9466 day or night

SOURCE: I bought a Utilitech 7 day digital in wall timer,

HI .. if the switch has only a black and white wire attached, and there are no other wires in the wall box, then you cannot use this timer switch. You need to return it and get a timer that does not use a neutral connection. The wires you have are a switch leg from the light and there is a white wire but it is not a neutral.
If there are other wires in that wall box , tell me and we can chat more about how to remedy this .

SOURCE: Help with Woods 59018/59028 7 day digital timer

The usual connection for this type timer is the house black power to the timer black, the house white power to the timer white and the , the light black wire to the red timer wire.
If you only have two wires, one black and one white, at the switch location, then you cannot use this style timer , as it needs a neutral. You should return this timer and get one that does not require a neutral connection.

SOURCE: I have purchased a Utilitech

What you have a single pole light switch you are replacing with the timer. As you say you have 2 black wires. One black wire is the incoming power wire and the other black wire goes up to the light. On a normal single pole switch is makes no difference which of the screws you connect it to. Of course with the exception of the ground screw. Tie all the white wires back together that are in the wall box and shove them to the rear as they are not needed to make this connection. The correct connection is to connect one of the black existing black wires in the wall switch box to the black wire on the timer. Now connect the other black wire to the blue wire on the timer. The red wire is not used in a single pole connection and is only used in a 3 way switch connection, so just put a twist connector on it and shove it back in the box. To recap, connect black wire on timer to either black wire in box. Connect the other blue wire to the other black wire. Do not use the red wire. Hopefully you did not hurt the timer by connecting it incorrectly. If it does not work after setting the timer up according to the instructions you have ruined the timer by wiring it incorrectly. Hopefully no damage has been done.

SOURCE: I lost my Leviton 6230M 30 mins timer installation sheet.

Switch has 2 black wires. One black is hot wire. One black is wire going to fan. Turn off power. Remove wires from switch and separate. Turn power back on. Using ordinary tester, test each black wire to bare copper ground wire. Only one of the black wires will test hot. The other black wire goes to fan.
Timer black wire connects to black hot
Timer blue wire connects to black wire going to fan
Timer white wire connects to white neutral (in absence of white neutral, connect Timer white wire to bare ground)
Timer green connects to bare ground wire

Installing utilitech in wall countdown timer


None of the answers are helpful. First, this is a question about installation and not operation so clpalmer976 is worthless. And no, if you read the question it was not a 3 way switch. If you hook it uplike ridley says, the light is not powered. Read the question. The red wire powers the device. The problem is "If I connect the red to the white, the switch will work in a clicking, pulsating fashion." The red has to be connected. The last suggestion, there is on info on unitech anything on the site. They are all somethings that can't read and make this site especially worthless.

My Icon bathroom fan does not work by timer I have changed timer , transformer and electrics have been checked (with certificate) What next !


Which timer do your have?
Not all timers work with fan motors?
Are you adding a new bath fan? Or are you installing a new timer?

What transformer what checked? A transformer is used to change voltage. For example you can plug a Malibu outdoor-light transformer into ordinary 120V outlet and the transformer changes voltage to 12 volts so you can safely operate lights stuck into the ground around bushes. Or your phone recharges using transformer that converts ordinary 120Volt into very low voltage entering your phone.
Practically every electronic device in your home has a transformer ... microwave, TV, computer ... but I don't know why a bath fan would have a transformer.
Add a comment, and I will respond.

Countdown timers are made to work with bath fans.
Leviton countdown timers are stout product with 1HP rating.

It sounds like timer is bad.
Wiring sounds good. Make sure you don't have Load and Line wires reversed. Try reversing Load-Line wires and see what happens.
Another thing that affects electronic timers is line noise/interference. If replacement timer does same thing, then noise is suspect. Try timer on another circuit without fan. Try another brand timer. Update to newer LTB60 Leviton timer. Use cheap circuit tester from home center to check outlet on same circuit.

I nees 15 min. timer for my Newtone bathroom heater. I live zip code 94602 Oakland, Ca. Where to find. Thanks


You need "15 minute countdown timer" for a bath fan.

1) Following page shows selection of timer types and brands:
http://waterheatertimer.org/Countdown.html
There are push button electronic types and rotary dial types.

2) Easiest to wire is mechanical spring type countdown timer, FD series.
No electronics that can be affected by 'electric noise' on fan circuit.
Intermatic spring-wound last for years without problem.
http://www.electricsupplyonline.com/prod/intermatic-springwound_timers.php

http://www.electricsupplyonline.com/prod/intermatic-springwound_timers/fd15mc_w005485.php

3) Another reliable timer is GE 15088 sold at Home Depot.
Timer has preset for 20 minutes, not 15
http://www.homedepot.com/webapp/wcs/stores/

4) Amazon sells reliable 15 minute Intermatic electronic countdown:
http://www.1000bulbs.com/product/3293/ELEC-EI200LA.html?utm_source=SmartFeedAmazonProduct

5) Timex sells 15 minute spring wound countdown timer. Lower price is probably with reason since Timex are generally sold in drug store/dollar store rather than hardware/electric outlets.
http://www.amazon.com/Timex-Minute-Springwound-Countdown-Timer/dp/B00013K69Q

6) Spring wound timers connect easily to same wires that come off old fan switch.
Old switch has 2 insulated wires, connect them to either terminal on spring wound timer.

7) Electronic timers are wired differently:
Instructions for wiring electronic timers appears on following link:

Also take advantage of fixya phone service.

L purchased a Lutron S2-LFSQ for our bathroom light and fan. l was informed by the store, this item was job specific so wouldn't have fan burnout. l now discovered stamped on the switches aluminum edging;...


Yeah, it matters.

The first thing is that the fan-speed in that control is only rated for 1.5-Amps. The issue with bathroom fans (I have to assume an exhaust fan) is not only how much current they pull during normal operation, but what happens if the fan rotor locks - that can pull some pretty hefty current slugs that the device is NOT rated for.

Also, generally speaking, putting fan-control on an exhaust fan doesn't work that well. If you slow down the speed at all, it significantly minimizes the amount of air-flow going through the room - which means you're using all of that energy for basically nothing.

My recommendation is to instead get Lutron's MA-L3T251- device. Here, you have the dimmer for the lights (same as the control you bought), and you have a timer switch that's rated for general purpose fan loads (up to 2.5A).

OLD wall timer Model E1020 ticks really loud


You probably can't get the existing mechanical timer to operate any quietier, since it's old and likely starting to wear out. You can either swap the timer out for a new automatic digital timer, or install a standard single pole switch in its' place.

I believe the code you refer to regarding the fan having to be wired onto a timer switch was a local requirement from many years ago.

Some local jurisdictions have impossed more stringent requirements, but frankly, having an exhaust fan is normally a good idea. If the fan is vented into the attic space, it can cause some serious problems in cold weather with condesation of the warm, moist exhaust air.

Building Code requires that bath fans be piped/vented to the outside of the house and not into the attic space.

There are newer preset timer switches that will turn on the exhaust fan for a fixed amount of time, based on which button you push. These are great as they will run the fan long enough to remove condensation from showers, etc.

If you're going to replace the timer, disconnect or turn off the breaker or power to the switch. Then simply install a new timer or switch by connecting the black supply wire to the bottom of the single pole switch, or to one of the black leads of the timer. Then connect the black wire going to the fan to the top screw on the single pole switch, or the other lead on the new timer. The white (neutral) wires should already be connected with a wire nut inside the box. Connect the ground wire to the ground wire in the box and if the switch box is metal, attach the ground wire to the box with a green grounding screw too.

You can now operate the fan with either a manual on/off switch or the new digital timer, whichever you chose to install.
