Are the wires different colors or is there too many of one and not enough of the other. Your bathroom switch should have black which is hot, white which is neutral, and green or bare which is ground. It should be the same on the timer, but may differ. The instructions should tell which wire or terminal is hot, neutral and ground.

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.

What is the intermatic e 1020 used for just moved into a house andits in the bathroom and makes a lot of noise.


The E1020 timer is reliable heavy-duty 24-hour on-off analog timer with replaceable trippers and manual override, rated 12 amps.
This timer replaces ordinary single-pole on-off switch.
Timer has extra white wire that connects to white neutral wires inside box to run timer mechanism, while mechanical single-pole switch does not need this wire.
I don't know what it is doing... maybe running the vent fan periodically, or turning on attic vent fan?
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#E1020
http://waterheatertimer.org/How-to-set-timers.html

For same timer, with less noise, install E1100-1200 aka the KM series in-wall analog timer. Or install digital in-wall timer, or replace timer with on-off switch.

My Tn111 timer is running hot with just a fan running


TN111 timer should not be hot.
All electrical devices generate heat, but the clock motor inside TN series is around 3Watts, and should put off same heat as 3 watt light bulb.
This timer is rated for inductive loads like a fan, up to 1/3 HP (horsepower). Some timers are incandescent only and are not rated for fans or HP loads.
1) Try plugging timer into different outlet and to different Load (light, fan)
2) Test outlet with cheap circuit analyzer from home center to make sure outlet is wired correctly.
3) This line of timers has limited 1 year warranty

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:

I'm trying to install this Woods 59008 automatic fan timer in the bathroom. My old on/off switch only has three wires....and I that a light switch next to that. The woods 59008 has a red, black, white...


Sure George.

These in-wall timers have extra wire to operate the electronics located inside timer.
You said your old switch has 3 wires.
The new timer can only replace on-off switch that has 2 brass screws and a green screw.
If old switch has 2 brass screws and a dark screw, that is a 3-way switch.
Typically a 3-way switch is found at both ends of hallway.
The Woods 95008 countdown timer is not made to replace 3-way:
http://waterheatertimer.org/Woods-timers-and-manuals.html#59000

Here's what to do:
1) Switch has 2 wires (plus bare ground wire). Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
2) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires. This wire will power timer electronics.
3) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
4) Turn on electricity, and push override button located below the OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

I have a paragon 8145-20 defrost timer. do you wire the compressor to the timer? I cant seem to find a wiring diagram on how to wire this correctly


Link below has wiring diagrams and wiring manuals for 240V 8145-20
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

I am not expert installing defrost timers.
According to information from Paragon, 8145 is for hot gas defrosting. 8140 series are time initiated, and pressure-or-temperature terminated.
Wiring diagram does not show compressor wired to timer.

The cycle works like this:
Timer is running but defrost is not switched ON.
Fan is ON.
Timer switches ON and activates defrost cycle.
Fan turns OFF. Hot gas valve turns ON for defrosting.
Cycle limit switch is temperature or pressure sensitive.
Cycle limit switch reaches trip point, timer switches OFF.
Hot gas valve turns OFF. Fan turns ON.
So fan is off during defrost cycle.
Hot gas valve turns ON when timer switches ON.
Timer is switched OFF by pressure-or-temperature limit switch.

I purchased the Legrand RT1 Time Switch to run a bathroom fan. It is installed and I see indicator lights. Every time I turn the fan on, it runs for a second and stops (hearing clicking in the switch);...


You connected red and white wires together.
No problem, nothing burned out, and it's simple to fix. Steps below.

RT1 is electronic countdown timer, and electronic timer clock inside needs separate circuit, just like your alarm clock needs to be plugged in. >> that's why timer has white wire. White wire completes circuit to timer clock.

Manual says:
Timer-black-wire to Hot; Timer-red-wire to Load (lights)
Timer-white-wire to Neutral.
Heres what to do
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires. Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground.
5) Turn on electricity, and push countdown button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

My house has a T1033A which controls the bathroom fans. There is no display and even when I turn the unit to the off position, I cannot switch the fans on. Is the unit shot? I can't determint which breaker...


Open following link to identify timer and download manual:
http://waterheatertimer.org/Aube-timers.html

The reset button is small round button and can be pushed with toothpick or paper clip.
If reset doesn't restore timer, then timer is probably shot.
Also check all breakers to make sure one isn't tripped.
To test which breaker controls timer, open up box so you can test wires, and then use electrical tester and process of elimination to identify correct timer.
Add a comment and say if this is new installation or if timer suddenly stopped functioning.
