Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater

1 Answer

Gas heater shuts off & won't come back on

We've been having this problem for several nights:

We have a gas heating system. At bedtime I turn the heat down and it completes it's cycle & then shuts off. Then it won't come back on. We've tried turning it off & on, turning it up & down (we have an old style, manual thermostat) to try to get it to kick on, and nothing happens. When the house gets reallllly cold it finally kicks back on and runs continuously until it reaches the temp set on the thermostat. Then it shuts off again & won't come on.

Hoping that we just need to replace the thermostat! Whadya think?

Does off peak only heat up at night??? Will it automatically heat up when it cools???


yes only when the load from the power station is low at night, the water tank has a thermostat that turns the power off when hot . it does not heat during the day. Get the biggest tank you can if you use a lot of hot water in the day. We have a lot of sun so have a sola hot water system with a gas back up.

Rheem does not post service manuals, as consequence almost all water heater questions on fixya are about Rheem products. However other companies use same gas control, and have service manuals available that might assist.

Call for service technician.

Model md200tbe shuts off, pilot and burner


1) Try blowing it out with a hair dryer. Dust does lots of weird things to gas heaters.

2) There is a thermocouple that opens when it is hot and makes the gas keep flowing. It is a small metal tube that sits directly in the flame. When it heats up, the gas flows. If that is shot, then it won't keep the gas flowing, so it will turn off when you let go of the button. Try tapping it lightly with the tip of a screwdriver to knock it loose. There is about a 10% chance that this might fix it temporarily until you can get a new one.

WATER HEATER GOES OUT OVER NIGHT


you either have a back draft blowing out the pilot light, or a bad thermal coupling. if coupling is bad it will shut down the gas flow therefore shutting off pilot light. its a safety measure to stop the gas flow if pilot goes out. replace thermal coupling, that may do it. good-day ! but shut off gas first !
