Outdoor sensor won't work. Tried changing battery, no luck. Been trying this on and off for weeks. Any suggestions?

Have you changed the batteries in the outdoor temperature sensor?

Have you changed the batteries on the outside sender unit?

I am having the same problem. The manual says to avoid plugging into the same circuit as motors & fluorescent lights. Mine is on the same circuit as a freezer. I'm going to try changing the AC outlet to see if that helps. Good luck!

Hi Susuan,
One of these methods below should get your device working properly. Good luck!

The product information page
From the manual:
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE SENSOR
The atomic clock will receive the temperature data within 3 minutes. If the temperature data is not being received 3 minutes after setting up (the display shows "- - -"), then please check the following points:
1. The distance of the atomic clock or outdoor temperature sensor should be at least 6 feet (2meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference.
Note:
When the 915 MHz signal is received correctly, do not re-open the battery cover of either the outdoor temperature sensor or atomic clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature sensor to the atomic clock (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).

The Coleman website has them. Www.coleman.com Search for the HWOD product, then click Parts.

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

Most digital timers suggest resetting as last-step effort to restore functionality.
This particular timer is reset by removing battery.
Try removing battery again. Otherwise it seems the timer has gone bad.
HB88RC is discontinued product.
Replacement is heavy-duty Intermatic HB800RCL 2-outlet or HB800RCH 1-outlet timer.

Before buying new one, try with this step. Remove batteries from your remote and reset it after 5 minutes. And also remove DC wires plugged to indoor sensor display, and after 5 minutes re set it again. Now start your unit. Sometimes it will work out. Thanks.

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.

See if has a fuse anywhere. These are throw away items. It might be time.
